Is there anyway to bypass mDNIe on the Galaxy S4?
On the Galaxy Note II with Perseus kernel, one can use STweaks to "Enable master sequence", which will ignore Samsung's profiles and instead use a color scheme that closely calibrates the display to the sRBG color space.
My understanding is that a Note II display was measured with a colorimeter and values were obtained which allowed accurate color representation when the values were input into a mDNIe matrix.
In any case, is there any way to obtain accurate color on the GS4?
I noticed that Liquid Smooth ROM has advanced settings to set the color scheme (which didn't seem to do anything) and color temperature (didn't seem to do anything.)

Ive seen settings for mDNIe inside the KTweaker app that comes with the KTSGS4 Kernel. Not sure if its exactly what your looking for, but its the closest thing i could find. Might want to take a look at that kernel if you haven't already.

maybe we can get a monitor calibration app.....
There is a gamma check down the page here:
Monitor calibration and gamma
mine looks to be 2.6
This is a cool app:

I don't have any dead pixels!
On the gamma test there the vertical background is 2.6ish I guess but the horizontal background is way different.... Not sure if that can be adjusted somehow
Apparently adjustments have been made for other phones
I found this thread about the nexus one
[HACK] Calibration profile for Nexus One v5.1, now with 100% less Sith! - xda-developers
I'm unhappy with the colour saturation offered by Samsung's four display profiles. The default is too vibrant, and the next one down is very dull.
Can this be tweaked manually? If not, is it possible to write a mod which achieves this?
Cheers.
Hello everybody.
I find standart mod really too saturated but natural mod is also too washed out.
Could someone create a profile between them ?
Thanks a lot !

I'm not sure but I think display controls are all within the kernel and to my knowledge the only one where you can play with these is Perseus.
Here is a quote from the author of Perseus about the first implementation of display controls:

[*]mDNIe sharpness and RGB/YCM chroma saturation control in STweaks:
I started implementing sharpness control in STweaks and went a bit over-board instead of a simple checkbox; You now have controls over the mDNIe registers as a delta offset value compared to the stock register values. I'm applying the offset to all mDNIe profiles and scenarios which have the specific post-processing effect active in that specific scenario. Meaning, that you start with the default profile; Dynamic / Standard / Natural / Movie and have the delta offset applied on top of that.
Sharpness delta. This is what brought most of the quality difference in hardcore's original tweaks. You can now fine-tune it to your own taste, and also take into regard that it produces a different effect for each screen profile while having the same delta - the base values between the profiles are different.
DE control - I don't know what this actually does and I couldn't discern much difference between the values, but it used to be disabled in hardcore's tweaks.
Chroma saturation control: This is composed of 2 values for each RGB/YCM channel. See the Munsell color system for a visual representation of the values controlled here. The chroma curve control describes the curve weight based on chroma intensity, the chroma gain is the chromatic gain that is being applied on the respective channel. Chromatic saturation weight is again another multiplier for all channels combined. I have not managed to properly identify the chroma grey threshold and its effects.
Basically this is like an RGB control on steroids, and enables you to tune your screen to your own liking and calibrate it as you wish. Please note that not all scenarios in the profiles have chroma saturation effects, the Movie profile for example has no effect applied to the UI so chromatic control has no effect on it.
I also want to state that the above are my deductions and theories on the descriptions of these controls, I'm not familiar enough on colour theory to be able to confidently say that these descriptions are correct, and the controls are a work-in-progress for now. Experts are welcome to contribute here.
[*]Front buffer early suspend delay option for those who have issues with the CRT animation.
[*]Did some refactoring on the Mali drivers and fixed a bug which may have caused less capable undervolting than the stock implementation.[/list]

I've read the dev was looking for testers preferably with color calibration equipment, so more is to be expected.
I wonder if Supercurio is making some display tweak apps for the N2, Id really like to have the ability to change the color temperature as most if not all of the Galaxy Note 2's Ive seen are really steering towards the warm whites ( depending on the brightness and ambient light )
Thanks androssama.
I use redpill but I tried perseus too. I saw that possibilty but it seems to complicated to me (I'm a noob).
I'm gonna try again. Which setting should I change to get between the two profiles ?

In Miui You can change Display temperature From Normal To Warm Or Cool
But when using custom rom like Aex or Lineage i can't find that choice
the screen is really warm and white color is almost yellow
please i need any solution for this i want to make the screen contrast cool Like Miui
Thanks i really appreciate your quick answer
Theres color profile option in livedisplay setting on los based roms, use that.
i tried it but it can't make white color looks really white

Use Kernel Auditor app..and if your kernel support kcal you can calibrate the display color profile.
Would You please Explain what is kcal ??????

Its an module for Advanced color control for Qualcomm MDSS 8x10/8x26/8974/8084/8939.. your kernel have to be supported to make fully use of it. check thishttps://forum.xda-developers.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080
The los livedisplay also got manual color calibration option, that should be enough to tinker by your own to get however white you want.

Not really...on livedisplay there are only tweaks for the screen RGB color which is not enough in many situation...in KCAL you have screen value and contrast value and minimum sRGB value those are valuable option to tweak... that's why I've told you...now its up to you.
The blue light filter is absolute garbage on the Tab S7, and you're unable to change any display settings beyond Vivid and Standard.
Does KCAL support for this device exist in any way? I am rooted, and would prefer to keep OneUI if possible.
Cheers
