In the /r/OnePlus subreddit, many OnePlus phone users that have the updated Photos app are facing issues with a weird green or yellow tint when viewing images in Google Photos. Google Photos will be the biggest app yet to support color management, and users are already facing issues. However, Google's color management system is still new and barely used in Android, and because of that, not many OEMs have had the opportunity to really test it out to find issues in implementing the color management system that Google introduced in Android 8.1 Oreo. This is how it's roughly handled in Android for supporting apps. Color management can get really complicated, but put simply, an sRGB display calibration should be used to properly display normal sRGB content, and when displaying a P3 image, the display should switch from the sRGB display calibration to a P3 display calibration. On the software side of things, there's a lot going on.
