My 14 day return period is expiring on Sunday, so I need to decide whether to keep my current unit or try to exchange it. I have a small amount of purplish light leaking from the bottom of the screen. It's only becomes noticeable in a dark room at near max brightness. It looks like this (not my pictures): I know that no LED panel is perfect, but is this sort of leakage considered acceptable? I'm hesitant to exchange it because I'm scared of getting a unit with even worse leakage or dead pixels or what have you.
