Hi all,
After reading this, especially this part:
"Suggestions for Google:
1. Eliminate the primitive 16-bit display interface and fix the Browser, Gallery and other applications.
2. The White Point is too blue, lower it to D6500, which will improve color accuracy, slow the aging of the Blue OLED, reduce power consumption, and improve battery run time.
3. Improve the factory display calibration to correct the large color and gray-scale tracking errors and the irregular and non-standard display contrast and Gamma.
4. The color saturation of the display is way too high. You can trade this excess color saturation to boost the screen brightness by adjusting the software color calibration matrices. This will also improve the color accuracy of the display.
5. Take full advantage of the OLED display: the ambient light sensor now just controls the screen brightness. You should also use it to control the gamma, color gamut, color saturation, and edge enhancement so that in low ambient light the display delivers beautiful and accurate image and picture quality, but as the ambient light increases slowly turn up these parameters to counter-balance the washed out appearance of the images in bright ambient light. Also add a display Vivid or Pizzazz control because some people prefer punchy images and pictures, while other people do not.
Nexus One Conclusion: The Nexus One Display Looks Like a Prototype
The Nexus One OLED display has many spectacular qualities, but it is also loaded with lots of rough edges, hasty unfinished beta display drivers and Android software including principal applications like the Browser and Gallery, poorly implemented image processing, poor system integration together with sub-standard factory display calibration. It really looks and behaves like a prototype for a very nice future display, not a finished production display for a world class mobile device that Google markets it to be. It will be interesting to see the degree to which existing units will be corrected and improved with software updates."
My toughts are: could it be possible to tweak video drivers, or at least modify gallery and browser apks to achieve a better viewing quality?
Someone give this man a beer I couldn't have said that better myself.

Any devs watching this?
Wow...even more improvement possibilities! Modding this phone seems endless!
Yeah, I seriously believe we could improve display performance with some tweaks. I noticed that on the iphones 2g,3g,3gs and 4g, the screen kept changing color and it really did make a difference. Like the 3g screen seemed a bit yellow and 3gs was more natural and they kept on improving.
I would like to hear some dev's opinion because I think it's pretty hard to modify video drivers, as we are seeing in the "porting video drivers" thread...so I'm not too optimist...but let's see what happens

As a pro video calibrator I would LOVE to have an app that allows me to change the RGB levels so I can set the grayscale.
I will watch this thread with great interest. Here is to hope.
I think the start is with the rendering tweaks that is being used in cm6. Where that is, I have no clue on the technical specifications..... Sorry.
How many of the issues are hardware related though? They're certainly not going to be updating those.
I'm pretty sure I read that article a few months ago, Google appear to be quite reluctant to do anything specific to the N1 and prefer to just keep trucking along with the generic AOSP development. If anything that can be done is going to happen, it'll be due to the clever developers on this and other forums.
The N1 display looks like it's permanently in store-presentation mode, very sharp and contrasty, unfortunately it's not very realistic. If changes can be made in software to improve things, that'd be great, but I doubt it'll be Google doing it.
grayscale
Would it be possible to have a setting to make the entire display grayscale instead of color? If so, would this then allow us to punch up the brightness past it's default levels? Battery life is not my concern. Seeing my screen in the bright sun is though
Alright, I checked it out using the patch that enables nightvision mode in later CM builds, a calibration profile can most likely be done. I'll get my colorimeter tomorrow and use changing linear transformations to turn one of the modes into a calibrated profile. It's up to Cyanogen whether or not it should be added "officially," but I can just overwrite salmon or something and post an update.zip in the meantime if I can get it to work.
Lowering the contrast (and calibrating for that matter) will lower the total colors that can be rendered, so you'd have to keep that in mind. I'm not sure if the screen is 16 bit minimum (at the lowest brightness and thus the more detail the brighter it is) or 16 bit maximum (at highest brightness) as darkening the "backlight" would just narrow the gamut on the device, anyone know? The gamut may already be too narrow to justify a LUT, but I'll see soon.
From what I know, the system is capable of 24bit color, but only 16 bit native. You see, OLED displays have really high refresh rates, so they show the color above and below the target in the right ratios to trick the eye. I don't think the system does these calculations when it expects the screen to move, too high a load, and that's why tapping on the screen in the browser changes colors. This is probably just the application using the wrong settings with regards to it.
The pentile matrix can show fonts really nicely if it has the right font hinting. I've heard that it doesn't, however. I'm not sure where you'd find the best place to go about that, but it's probably out of the kernel and thus outside of my knowledge..
Edit: heavily edited for cleanliness and new knowledge.
Great contribution Storm...do you think we can correct issues noticed in FIGURE 1 (nexus vs iphone comparison) ? It would be AWESOME ...
Maybe should I open a similar thread on cyanogenmod?

we all doubt it...that's why we're unlocking FM radio and add 720p recording...N1 could really have been the iphone killer if Google did the job ENTIRELY...but really seems that N1 is an unfinished prototype, combine this with huge errors (no marketing and online-only distribution) and you have a partial failure, I know it's sad to say...
Still love my N1!
Well, it looks like the calibration profile is going to be [1, .98, .69] [R,G,B] or thereabouts. Can anyone test the temperature with their own calibrator? I'm getting 9300K when we want 6500K, the website noted earlier got 8900K. I'd like a few more test results but I can work with just my own.
I'm going to edit the files and try it out on my phone here soon enough. I can, if I can modify by-pixel colors, calibrate it to a 2.2 gamma, which would lower battery usage and the overly contrasty and cartoony colors significantly. It'll take a while though if it's even possible.
Anyone know any good apps that just show a specified RGB value across most or all the screen?
Edit: Alright, there are two calibration profiles, one for the lowest brightness, one for the highest. The values I'm getting (for the code junkies) are [1, green, .82] for bright screens, and [1, green, .80] for dark screens. The problem is that the level of green is pretty subjective. I can't measure it without doing extensive calculations, but comparing it to my calibrated monitor, .98 or .99 seems good. 1.00 should be ok, as .98 will add banding.
I'll upload the libsurfaceflinger.so with the modified profile for people to test in another thread (to be linked once I make it here)

This is awesome! I will certainly test tonight with my X-rite i1 Pro meter. Just curious, where are you getting the IRE images from?

As of now, I don't have IRE images. I just calibrated the white point, and even then, kinda inprecisely. Your data and inputs are valued, but I can't do anything more than a linear equation on the pixels. Currently, I keep red as it is, multiply green by .98, and multiply blue by .82 . It's not accurate, but it's close, and it uses less power. The gamma is still skewed to hell though.

Of course it's relevant, this thread gave me the idea for that. A few posts up is me debating whether or not it would work.
Does anyone know where I can see an image the compares the different settings of the "Background Effect" setting? I've read that this adjusts the color saturation of the screen. This is a concern to me because I saw the Samsung Infuse in person and the screen was far too saturated for my taste. For just looking at icons and email it was fine. But when looking at photographs, the colors were far too saturated. Sure they "pop", but they're not accurate. I was wondering how the Galaxy S II compared at its different settings.
Thanks.
To be perfectly honest, colours on the GS2 aren't accurate at all. However, if you change the background effect from standard to movie (the lowest setting) it gets close and looks a lot better.
Is it feasible that selecting 'Movie' over 'Dynamic' will aid in power conservation efforts?
I've been using the 'Movie' setting with minimum brightness for almost a week and today I tried the 'Dynamic' setting with full brightness again and after 5 mins I couldn't look at the screen any more, my eyes were in too much pain!
I'm also wondering about the impact that background effects have on the battery. I have seen couple of battery reports of people using 'Movie' and they seemed better than I would have expected after looking at their usage.
Yes movie should save a little power. Dynamic is like"torch" mode which is
The mode shops usually have their tv's set to when selling them to show off
The tv.
My samsung plasma tv has the exact same 3 settings, movie draining the
Least power as it is not as bright as the others. I would think the same principle
Applies to phone screens too.
I will openly admit that as a fan of AMOLED displays, I love the "oversaturated" colors and "better than life" images they facilitate. Of course there are people who prefer LCDs and people who are color-accuracy purists, and I respect their differing preferences. With that said, I want to offer some comments about the Galaxy Note 7's display, and see if other people are having the same thoughts. For reference, mine arrived on Tuesday of this week so I've had it for roughly two days now.
The sAMOLED panel on the phone, or at least the phone I have, is a horrid disappointment. The first thing I do when getting a new Samsung phone (which for various reasons is basically every time a new one releases) is turn the Display Mode to "AMOLED Cinema". Until the Note 7, it had been the most intense, color saturated setting option. With the Note 7, it looks awful. The colors are washed out and "dull" to the point where I almost wondered if there is a calibration issue. Oddly, the Automatic mode seems to be the only way to get colors remotely saturated to the point of which I prefer.
Along with the Note 7, I am currently using a Nexus 6P. The display on the 6P is, for my personal preferences, far better than that on the Note 7. I have the same wallpaper on both, the same icon set up, and yet the 6P's colors look way more intense.
Has anyone else noticed this? In particular, people who have owned the Galaxy S7 Edge, the Galaxy Note 5, and the Galaxy S6 Edge+? Could it be that my device has a problem with the panel?
I used the S7 Edge for about 4 months and at no point did it have the color "problems" that I am experiencing with the Note 7. Mind you the smaller, standard Galaxy S7 looked more vibrant, but this was attributed to the display being that much smaller.
Yes, I get the idea that Samsung is trying to make the displays more color accurate and whatnot, but in all honesty, should the ultimate goal be to make them as close to LCD color calibration as possible? Is that what people would want?
If this is where Samsung is going with future products, I must admit I'm not happy at all. Part of the reason I like the Galaxy series has always been their super saturated situation. The Note 7 is now the first product where I have, from the very first minutes with the phone, been unhappy with the display.
Any thoughts?

I also heard about this lowered saturation on a YouTube review video recently, so it looks like Samsung has responded to the stupid complaints about the over saturation. I am on your side here as I love the over saturation, it is fundamentally why I go for Samsung phones overall. Those that complain are too dumb or too lazy to go and change the levels in settings. So Samsung has helped quell the moaners.
I am waiting for mine to arrive on Tuesday and I will report back here. I hope it isn't too noticeable as I will be bitterly disappointed.

I am in the 'other' camp and much prefer a more natural picture, close to SRGB. Even then I use SCREEN BALANCE (app store) to very slightly change screen tint to a more blue'ish hue to get white whites.
My gf has a 3 series samsung and the colours are imho truly awful with their over emphasised vibrancy.

I think the S3 is not the best phone to compare it to. Back then the displays were really off balance. But I respect your preference for a more natural look but surely we need the options for either. Can the SCREEN BALANCE app you mentioned be used to saturate the colours at all? And does it interfere with the screen overlay issue when setting permissions for other apps?

I suspect you will be disappointed. I am literally, at this point, going back to the Nexus 6P constantly for web browsing and YouTube.
You are insane. Yes, Samsung changed the screen modes for the BETTER.
Basic = sRGB = most consumer content.
Photo = Adobe RGB = pro photos
Cinema = DCI-P3 = film making standard
Adaptive = oversaturated, cold white point that some people like yourself prefer.
Cinema used to be the oversaturated setting. Now it is adaptive display. If that isn't saturated enough for you, get your eyes checked dude. Beyond that point, you are absllutely making everything completely unrealistic. I don't like "washed out" aka accurate colors either, but I don't like colors that destroy the image. The 6P out of the box is too saturated. I have to tone that down slightly to match the Cinema mode from Samsung.
And people... STOP SAYING LCDS ARE FOR COLOR ELITISTS AND OLED IS OVERSATURATED. That is a crock of ****. The only reason Samsung made their first OLEDs oversaturated were to get people's attention. When using a calibrated setting, OLED is superior to LCD in EVERY WAY. Infinite contrast is A HUGE factor for image quality. LCDs suck. Period. The only advantage they have is brightness in TVs, which could change as tech matures (but Samsung has brighter OLED phone panels than any LCD competitor), and producing a deeper red color with quantum dot. That's it.
This is absolutely the best phone display ever made. Period.
Seems like people can find something to complain about. Now if someone has a truly faulty display, then that is reasonable to gripe about. But I can say my N7 has BY FAR the best display of any mobile device I have ever owned (Owned note's for 4 years now). This display is light years better than what my N4 has. The whites are far whiter, the colors are far better. It is saturated perfectly (I am using adaptive) and the brightness is awesome. The N7's display has already been shown to be by far the best display on any mobile device to date, and by a fairly wide margin in many of the different testing criteria. IDK what to say to someone who actually doesn't like the N7's display. Except maybe you have a faulty display. Each to their own, but it is pretty clear cut after extensive testing by displaymate (I think that's the site) that the N7 has the worlds best smartphone display. Second best was the S7 edge. I will say that I am not overly fond of the curved edges, but that would be my only gripe and has nothing to do with the actual display/brightness/colors/sharpness etc.

I noticed this the other day when comparing to my note 4 watching 4k videos. Videos were a little washed out and it didn't pop on my note 7. Details and contrast were missing. So I start looking in to the settings and in the Advanced features I find "Video enhancer" all the way on the bottom. I saw that it was ON and it makes the sample image brighter. OFF caused it to get darker. So I decided to turn it off and watched the same 4k video. Now my note 7 is exactly like my note 4. Colors popped, more contrast, more details. I assume because turning it off did not allow darker colors to get brighter and blended less with lighter colors of the same shade? Anyway, try it out yourself when you get your phone. I am leaving this setting off.

I agree about it being the best display. I absolutely have ZERO complaints about the colors. I recently upgraded from the Galaxy S5, and lets just say... the difference is mind-blowing. However, this boils down to preference, and there's nothing wrong with the OP's wish for more saturation, as that is just what he prefers. However, I find the most saturation comes with Adaptive Display also, while Cinema Mode seems a tad more dull. The difference in modes is hardly even noticeable though. To the OP: Just roll with adaptive, my friend.

Well, I don't know if "insane" is the proper word though. People have different preferences. I'd be willing to bet that a wide segment of the general population would also agree with me, and probably associate AMOLED with those exact "over the top" colors as some allege. Indeed it comes down to personal preference. Like how for some they simply can't use a point-and-shoot camera because the images are "terrible" but for the masses they would never notice most of the minutia of detail differences between a DSLR and point-and-shoot upon a quick glance.
Indeed I keep going back to the 6P now because the colors are so much more saturated. Which is ironic because when it launched last year IIRC, I felt it was too "subdued".
As for the generalization, I think it's become that way because many of the LCD-enthusiasts use that as their mantra. It's better because of X,Y,Z, basically the points you raised above. Perhaps when AMOLED becomes more common people will start to be more aware of the details and whatnot.

For me at least, the display saturation has been one of the primary reasons I will come back to Samsung. For example I loved the LG V10 last year but ended up getting rid of it in favor of another Galaxy S6 Edge+ simply because of the color situation.
I don't think the display on mine is faulty, just that I'm not so happy with the changes Samsung has made to its display setting profiles. As for the Display Mate issue, I've heard about it for a relative while now, but at least from my personal preferences it's a strike against the phone. It would be interesting to see what a large segment of Note 7 users feel about the display, though I'm willing to bet that (1) 99% don't even know you can change the display settings, and (2) the phone is already set to Adaptive thus people won't even be aware to begin with.
Just as a side note, I found the Sony Xperia X to have a stunning display in terms of color saturation. They have calibrated it almost to the point of being an "old school" sAMOLED.

I understand what you are saying. I do not disagree with you that the display has been praised highly by the likes of Display Mate, I don't even dispute that this is the best display ever on any phone. I welcome the better whites and brightness and all that you point out and I also despair at some of the negativity posted on XDA about the Note 7 in general.
But I can't help the fact that I love over saturated colours on a phone (not necessarily for photo's and videos but certainly the UI) and up until now this has been a predominant feature of AMOLED. What I am complaining about is that the option to have a natural look or a vivid look that has always been a built into the settings for the display are no longer adequate. From what I gather, the CINEMA mode which was always the most vivid, makes little difference now. How hard would it be to allow users more control over saturation? The issue therefore is not with the display, but the software settings.
If as you say the ADAPTIVE mode is sufficient then I will be happy with that. Until I get my phone I won't know for sure.

I guess you could. Why not try it?
Yes it works by way of screen overlays. Certain application, like my mobile banking app require SB to be switched off. No biggie.
It may be of interest to you that NOUGAT has built in colour sliders and white balance adjustments which work at root level. Well at least the development version had it. Whether this makes it into the final version is another question. I can imagine that some manufacturers which have spent some effort to get their displays calibrated as close as poss to approved standards may object to see their work compromised that way.
We have to see.
I think nougat has been rolled out on Nexus so may be worth looking there too.

But I can't help the fact that I love over saturated colours on a phone (not necessarily for photo's and videos but certainly the UI) and up until now this has been a predominant feature of AMOLED. What I am complaining about is that the option to have a natural look or a vivid look that has always been a built into the settings for the display are no longer adequate. From what I gather, the CINEMA mode which was always the most vivid, makes little difference now. How hard would it be to allow users more control over saturation? The issue therefore is not with the display, but the software settings.
If as you say the ADAPTIVE mode is sufficient then I will be happy with that. Until I get my phone I won't know for sure.

An excellent point: why doesn't Samsung allow manual tinkering of the color saturation? Why not add a "Custom" mode? It has one for the music equalizer for example.
Rival products such as Asus hardware (though the Zenfone 3 crashed every time I tried) and even the BlackBerry Priv have manual color saturation sliders. If Samsung is so interested in changing the settings to inevitably upset any number of people, why not also have an option to tailor the display to the user's liking?

In theory you are correct about that but if you put maybe 5 note 7's side by side and set them all with the same color mode. probably 4 out of the 5 devices will have different color temperatures and saturation.

Yes, there is a margin of difference in each screen - no calibration setting is likely to produce the same result in a different screen. But unless Display Mate received a cherry picked device, or got extremely lucky, their testing shows these color modes are very accurate.

That is a great point and something that really should have been incorporated. OEMs are hesitant to allow users to customize things, which is stupid... Samsung wants locked bootloaders. Apple locks damn near everything down. I think the reasoning behind this is because most people don't have a damn clue what they're doing, and it would lead to devices with really bad configurations either by accident or by ignorance. The owner would think something is wrong with their device, other people would see this and think poorly of that OEM, there'd be improper repair/warranty claims attempted, etc.

One. You're pitting your subjective preferences against a PhD holding expert that tested the display using a battery of standardized tests using sophisticated equipment.
Absolute Color Accuracy for Each of the Screen Modes
For each of the Screen Modes we carefully measure the Absolute Color Accuracy using an advanced series of spectroradiometer measurements with 41 Reference Colors that provide a detailed map of the Color Accuracy throughout the entire Color Gamut for each Screen Mode.
Absolute Color Accuracy is measured in terms of Just Noticeable Color Differences, JNCD. See this Figure for an explanation and visual definition of JNCD and the detailed Color Accuracy Plots showing the measured Color Errors for the 41 Reference Colors for each Color Gamut. For all of the calibrated Screen Modes, the Galaxy Note7 has uniformly Very Good to Excellent Absolute Color Accuracy. See our detailed Absolute Color Accuracy Plots with 41 Reference Colors for the 3 calibrated screen Modes and also this regarding Bogus Color Accuracy Measurements.

Wait a sec I think you might have misread or misinterpreted my original comments. I never claimed the display was in any way inaccurate, in fact IIRC a point was even raised about my having seen the analysis reports and such. My comment was purely a subjective one, that I don't like the new calibration in light of a personal preference towards truer-than-life color reproduction on a display. My asking for comments was not to challenge the accuracy of reports stating the Note 7 is properly calibrated, rather it was just to reach out and see if anyone also preferred the "old style" color tendencies.
IIRC someone in this topic mentioned about how Samsung might not want users to play with the calibration settings (thus no manual control) as it would potentially lead to creating a bad impression for anyone who saw any given user's device and didn't like the color reproduction. But I would argue that this is the inherent problem of Android, and OEM skins to boot. Just looking at some of the people here in Japan, and the phone(s) they are using with absolutely grotesque levels of carrier bloatware and skins (NTT docomo is by far the worst), I often feel Android is being misrepresented both to the user and to the market itself.
Many times people have said how "my phone is so slow" or "I don't like all these apps on it" and I've tried to explain how that's entirely the result of (1) the Docomo skin, or (2) the fact that it's a carrier model. Now adays more people are starting to at least know OF factory unlocked products though actually buying them is another issue entirely. I'd wager anyone not actively interested in tech around the world really has no interest in spending the better part of 1K on a top-end flagship sold factory unlocked. Thus people take what they can get for as low as they can get it for.
Anyway, going back to the original topic of the display, Samsung really shouldn't worry about how users might "sully" the beauty of AMOLED given that carriers already do enough to cause even the best phone(s) to be "broken" and that shapes someone's impressions just as much.
Now I actually have the Note 7 my anxiety over the colour saturation and screen modes has been eradicated! The display does not disappoint in any way and adaptive mode is surprisingly. . perfect!
I notice the difference between my Note 7 and my Galaxy Tab S, they look different but the Note 7 is equally good.

tokyoguy, Really, I dont know what device you are talking about, or got yourself a really, really defective one, my screen is the best I have ever had, I hat 4 other samsung models, 2 sony, etc, this one the note7 is the best for me
Are u sure that opx is true black amoled??
What if I say you ... that ..It has a backlight ..
Wanna verify?
Important: make sure u have brightness slider to near low levels. This backlight is not seen at high brightness levels.
Download a gallery like quickpic that lets u open a picture in Fullscreen mode so that picture fills entire screen.
Make a bmp image in ms paint in windows and fill it with perfect black. Or download from some website with hex value coding -enter zero for all numbers
Now load this picture in quickpic or any other Fullscreen gallery.
Switch off every light in ur room .make d room jet dark
Wait a few seconds for your eyes to adapt to darkness
U will see the backlight instead of black.
For more easy recognition see in peripheral field of vision, where low light vision is good. (Focus point of eye doesn't have low light vision ,am a doc.) (see somewhere else, bring in the phone into vision filed)
If u think the gallery is d problem.
Do this same thing in any other amoled phone. You will know the meaning of black.
(I did in Moto x ghost )
It's not a backlight. No AMOLED screen uses a backlight. That would defeat the whole purpose of AMOLED.
What happens is, even if the pixels are black (switched off), they are fed a tiny amount of voltage from the motherboard to allow quick switching of colors so they are never completely turned off. As a result, even when displaying black they emit a very faint glow.
I'm not sure if this only happens on pentile displays (like the one in the OPX and most Samsung phones) and I can't verify since the only AMOLED devices I own are pentile, but my Galaxy S3 Neo also has this "problem". Personally I wouldn't worry too much about it, since even with the glow the blacks are WAY deeper than any LCD display with a backlight can produce.

Thank God man.
I thought my phone is fake display.
Ur reply is proof that knowledge helps..
Btw just curious.. what are you?? How do you know this information not available in internet... So nice to see you man.
And regarding ur doubt, whether this happens in non pentile array amoled ...
NO.
I own a RGB amoled -Moto x ghost phone. It doesn't happen there.
I will check in moto x droid turbo . My cousin has it. So I will do and post results here.
And I wish to add this :
A 312 ppi RGB amoled (I have moto x ghost, 720p, 4.7 inch) is way better much much better than 440 ppi pentile amoled ( I have opx, full HD 5inch)
If I compare the images, they are much cleaner and sharper than opx . It's like the image has a depth, there is some stillness kind of feel. ...( I use colour control kcal, and so I test the displays in many settings not just default.
For example to make the images look similar as moto x ghost so that we can compare, I use rgb values as 32, 30, 27 value at 123, contrast at 121 and then slide the brightness slider to 3/4 or more.
Now both images look same in terms of how much dark areas are visible , the white wash noted in opx is now gone.
Now the images are ready for comparision.
Now the difference is the sharpness or clarity in rgb amoled. The feel difference i get is that there is depth in RGB. Its has a grip.
If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the LG G6's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!
The LCD is fairly color accurate all considering. This screen is very close to what I achieve using a hardware color calibrate with my work machines. The reds are not too red (faux saturation) and the cooler tones show up as prominently.
It's just a shame I can't hook up a hardware calibrator to it to test it.
Solid color accuracy
I am coming from a OnePlus 3T, so when first firing up the G6 I was a little disappointed. I couldn't believe how much more vivid the AMOLED screen was compared to the LCD. Well, now that I have been using the G6 exclusively for the past two days, I am growing quite fond of this screen. The colors are quite accurate and precise, just not as vivid/saturated as what I was looking at for the past 6 months. Liking this phone more and more each day.
The screen color temperature is definitely on the cool side, certainly higher than 6500K.
It is not pleasant at first for me. I've been using Nexus 6P on sRGB mode for more than a year, and the color saturation on the G6 under default, out of the box settings is disheartening.
To somehow mitigate this, what I did was to enable ComfortView, set at Low Setting. It's far from perfect, but that's better than nothing.
How is this compared to the S8/+ ?

From what I saw side by side compared to the S8+ at full brightness, I could see the whites having a more pinkish hue very slightly than the S8+. The S8+ having brighter highlights. Obviously, the S8+ also has deeper blacks, more saturated, and viewing angles are much better because of its AMOLED display. Other than that, the overall range of colours seemed fairly close between the G6 and S8+.
Not sure who will see this but I think the G6 LCD screen compared to an amoled like the one's on the oneplus 3/3t/5 and the s8/s8+ is just better in certain scenarios. There are some people who might be audiophile esque and want high fidelity and things like that. And there might be some people who like bass boosted beat headphones and other things like that which are not accurate at all but are enjoyable on a certain level. If you like big bass sound and you are that kind of person then you will like the amoled screen but I am personally not. I like knowing that what I see on my screen is what it is supposed to look like.
For instance the other day I was looking at a picture of the fifty shades of gray poster. It is supposed to be black and gray but it had a colored tint to it on the s8 compared to a g6 which looked as it should. All I am saying is that there are going to be times when the s8 because it pops colors so much will make what you see innacurate. And that might bother you or it might not. But it bothers me.
Exactly what Scape said. Tech people who know their stuff want accurate color reproduction and analytic sound. The wide mass wants flashy Colors and boomsound. Easy people rate phones by how saturated the phone looks. The more saturation = the better. This is complete BS for people who have knowledge about Electronics. Its like comparing people who buy a Classic car and put Chrome rims on it not caring for the paint because "CROME RIMZ M8". Where there are also people which buy a classic car, care to make it look as original as possible and know every part of their car.
The 2nd. Car may look boring to people, but its quality and worthwise extremely preferable. For example a natural Color reproduction can help when taking photos with the G6. If you take a photo on the Amoled Screen of a Galaxy, and then open it on your calibrated IPS, you will be flashed about how different it looks then on the phone. Thats not what you want.
Regarding the Bass... Well i like perfect color recreation but i hate neutral speakers or headphones, im quite a basshead but i still want a good clarity, deep stage and low noise.
Guys did anyone you tried screen color adjustment under settings-accessibility ?

Yeah, i kept my custom color setting enabled for a few weeks since the blue color looked way better. It is only when switching back to the default setting that i noticed how washed out the reds looked. I reverted back to the defaults.

I bought G6 after iP6S+ and I'm really disappointed from display over all. Blue is on G6 boosted as hell. At home I have calibrated displays and iPhone is much more closer. I can't watch photos (photographer) on G6 because of it. Even automatic brightness control is not ok for me. It's still dimmer than I want. LuxLite solved that but colors are terrible.
Why my phone is reporting me that I have screen resolution of 1440x2703 and PPI 544? https://imgur.com/a/lNXhw
Hello.I have Canadian oreo g6 and since the update the color s are more saturated.I held up the screen to my samsung amold screen and my g6 is matched if not better

This is bad news for me, I find the G6 screen beautiful (I am under 7.0) and I do not like at all the rendering amoled screens, precisely because of the saturated colors..
I found on 7.0 that the flesh tones on netflix and terrarium tv were way washed out.looked like everyone never saw the sun lol Na just saying I think LG just corrected the saturation a little bit to not make things so washed out looking.The reds are a little darker also instead of a orangey yellow tint.And like before the greens were not as dark .kinda reminded me of a mint or pastel green.Now on Oreo it is a true green and red.
Is there any app or any online guides to correct the LG G6 color accuracy and get true neutral white balance?
I have s8 and G6. I hate Amoled with that compotish colors. White is not white. Ever with pink or blue or yellow. Amoled is like woman with silicon tits. Far from reality. For me LG and Sony make most better displays.
Does anyone use this? I did for a while. I found it very good at adjusting the blues making them a bit darker FB looks much better IMO after I adjusted it
