As seemingly the majority of phone (1)'s have the green tint issue (even if some just very slightly), I was wondering if there are plans to address the issue via software updates.
One thought I had was for example a feature to overlay a gradient with a complementary tint, of course customizable by the user since every screen is a bit different. This would need to be done on the same system level as the night light filter, so it doesn’t show on screenshots.
Here is a small example where I’ve added a darker purple gradient to counter the lighter green/cyan at the top of my screen. Not perfectly adjusted, but I think it shows the effect quite well.
