If you bought a new Huawei Google Nexus 6P Android Smartphone and you don't like Saturated AMOLED Display Colors, then there is a second option on Nexus 6p and that is sRGB mode. So if you don't know how to enable sRGB in your Nexus 6P Device, Here some simple steps you have to follow.
Open Setting > About Phone
Touch 3 to 5 Times > Build Number
Now you see pop-up (Developers mode enabled)
Go Back To > Settings > Developer Options
Now You See > Picture Color Mode > Use sRGB
