Mi A1 Color Calibration help

[Cheesetale]

I just replaced my Mi A1's LCD screen cause last one was broken. The screen color is now too cold, the whites are yellowish. I just factory reset my phone. Also I have this problem that tapping the back and activity buttons (physical button on the chin) when it is locked wakes the phone up, I don't want this cause it causes accidental wakes when it is in my pocket. Any custom ROM or apps that can help me with this? I also need gcam.
