How do I make buttons white in all apps on LG G5/Fix screen retention?

[Clutterz]

Hello, I have had burn-in/screen retention problems on my LG G5, and was wondering if anyone knows how to fix this. Also, when I set my home touch buttons to white, they are white in only a few apps, and black in all the others. Is there a way to make them white everywhere? I am running android nougat.

Same here. Doesn't appear to be too many people with this problem...
