Does anyone have a KCAL temp profile (or manual configuration) that matches or clones close to the stock color profile in MIUI?
Thanks in advance

Stock kernel (to my knowledge) doesnt allow any gamma modifications. Custom kernel (possibly CM) however does (in most cases), but might require third party apps (e.g. FauxDisplay). As for stock kernel alternatives, apps like Screen Adjuster might suit your needs.
you can also try Lux Auto Brightness. It sets brightness automatically (using the front camera as a light sensor) and that way you can see everything clearly in direct sunlight and when you're in a dark place, it goes far more darker than the stock adjuster allows you to go thus saving a huge amount of battery juice
these are my settings in profile editor section of the app (LUMA) :
DAY
luma 20 brightness -50
luma 120 brightness -30
luma 230 brightness 45
NIGHT
luma 1 brightness -50
luma 45 brightness -35
luma 100 brightness -15
I didn't mess with the car and cinema ones, because I don't use them
Hi guys,
in custom kernel we have the possibilities to change the RGB values but what we need is a saturation and constrast control to make the screen perfect. Is possible to add this control on any custom kernel? maybe some dev can reply to this topic to explain if it's possibile or not
In my opinion, the screen on the Moto G4 Play is pretty decent for a budget device -- aside from the bluish/cool hue of the color reproduction. This is due to the white point of the display being set to 8653K, far from the ideal of 6500K (Velasco, 2016). It could possibly be fixed with a software-based recalibration from Moto/Lenovo (I'm not holding my breath), but there are a couple of things that we can do to make it a little better.
If you are using CyanogenMod you have the ability to adjust the colors under display settings to take some of the blue and green out. This is probably the easiest method.
If you are running a stock ROM the options are more limited, especially for anybody with a variant that does not support unlocking the bootloader and rooting. You might be out of luck. The following steps are for anybody running the stock ROM with root. If you have not rooted or modified your phone yet please read the warnings on the respective threads.
1. The Kernel
You will need a custom kernel that supports color correction, specifically what you want to look for is KCAL MDP5 color control. The squid2 kernel supports this feature, and there may be others as well. http://forum.xda-developers.com/g4-play/development/kernel-squid-kernel-moto-g4-play-t3496641 Remember to make a nandroid backup of your boot partition before installing any kernel or superuser software.
2. The Apps
As far as I know you need root access to use any of the software that allows you to do color correction. To install SuperSu it currently needs to be told to use systemless root on our phone. This can be forced by creating a hidden file called .supersu in /data with contents "SYSTEMLESS=true" (SuperSU Beta, 2016). You can do this in TWRP / Advanced / Terminal by entering the command "echo SYSTEMLESS=true>>/data/.supersu" There is also a flashable zip here in the forums that can do this. Just flash the SuperSU installer after this. There are many programs that can make the actual color corrections. An easy to use one is available from xda developer savoca here http://forum.xda-developers.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080 Kernel Adiutor available on the Play Store can also be used https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor&hl=en
3. The Settings
In Settings / Display / Color Mode I set the color profile to Standard. In the Color Control app from savoca I left all settings at their default values except for setting green to 248 and blue to 237. This results in a more natural white point in my opinion. If anybody else finds settings that work well please share them in this thread.

If using LiveDisplay change the day color temperature to 5800k, otherwise in color correction set R, G, B to 100, 98, and 90.
I have used the default and srgb mode but both of them gives a yellowish shade to the screen , i want my screen to look cool and unsaturated . Can anyone provide the best tweaks in this colour saturation . I have elemental x kernel installed so i can tweak the settings .
Using 4.0.3 , rooted , elemental x kernel
Hi,
I use these settings (you can raise the saturation to 55):

Thank you , these were really nice tweaks , totally got rid of yellowish shade , screen looking good for now.
The saturation of Mi 5 's screen is too high. I prefer the standard mode(in setting-display-contrast & colors). After flashing 3rd kernel, the MIUI stock display option is invalid. And the screen's color come to unsatisfactory. It is not easy to adjust KCAL option manually. So if I can find some way to figure out the original color profile of Mi 5's stock ROM, and I can apply to KCAL?
btw, I have spyder5 colorimeter. If I can use it to calibrate my cellphone's display color?
