Idea: Screen burn correction app that figures out how to exactly negate your screen's issues by pretty much looking at itself in a mirror through the selfie cam, trying to display pure white, remembering the imperfections it sees, then tinting everything with the negation of that from then on.

Nobody seems to have made this yet. I think there might be things for tinting your screen in general, but it doesn't know the specific quirks of your screenburn. Most of the apps for screen burn recommend that you just burn every color over the entire screen that isn't damaged yet, so that they all get to be equally damaged, which seems like a really bad thing to be recommending.
