Android N: Screen calibration settings w/built in tuner - Nexus 6P General

With Marshmallow and previous version of Android, you had to root and flash a custom kernel in order to tweak RGB settings on your phone to eliminate the "warm" or "red" hue that many of these Nexus phones have. For the past year or so, this was the only reason I ever bothered rooting.
However, that's all changed with Android N. Google has FINALLY baked an RGB tuner into the stock system, allowing you to adjust the screen color to your liking.
To enable this you simply have to unlock "System UI Tuner" by pulling your quick settings drawer down and long pressing the little gear icon in the top right. Once you do this, it should automatically open Settings and show you the new System UI Tuner option. Once that's done just navigate to System UI Tuner / Color and appearance / Calibrate display. At this point you can drag the 3 bars however you want to tweak the RGB values. *Note, changes won't go live until you hit "Apply"*
Now, this isn't as intuitive as adjusting RGB values with custom kernels and kernel tweaking apps because you can't actually see the true RGB numbers. So you have to kind of just drag, test, drag, test etc. until you get it to your liking. With that said, I've spent some time tweaking mine to mirror the display color tones of my LG G5. To me, it makes the whites a pure white without being too blue and eliminates the warm hue my phone had from the factory.
Here's a screenshot of my setup:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
NOTE: All displays are slightly different and settings that may be perfect for one person, may not be right for you. Just keep messing with the settings until you get it to a color tone that looks best TO YOU.

I agree I think this is amazing. Look at all the devices returned and all it would take is a slight adjustment and they would be happy. These displays are top quality they just weren't calibrated perfectly and it's all preference but with this people can set the display up perfectly to satisfy themselves. Here's where I'm at right now just slightly adjusted to get a little whiter whites.

This has been removed alongwith Dark Theme.

Dark theme is still in dp3, but the ability to automate it is gone, it's in the quick settings menu.

There is not. Here's the screenshot. Only Night Mode exists now. Dark Theme option no longer exists.
And that would be removed in the final build as per reports.

Yep. I'm extremely annoyed that Google felt the need to remove this feature. RGB tweaking is the only reason why I root. I'm still holding out hope that Google will bring it back in the final release.

So, I set all of them to 0. Is there any way I can fix that? Phone screen is all black :/

Have you rebooted the phone? Do you have TWRP? Do you know how to use Fastboot? Might need to reflash

Fixed already. I rebooted into TWRP and then (when I didn't think about what to do) rebooted back to system. Maybe just a reboot works.

I believe it's removed in the official Android N release.

How would I go about RGB tweaking my nexus 6p with root?
