Went through a long checklist of things to watch out for and really happy that I had absolutely no issues with mine. Particularly the screen. I hate playing the display lottery and my panel has little ghosting, acceptable levels of blooming, and pretty good gray uniformity.
And tonight I notice this. First I thought it was just a speck of something to rub off. But it wouldn't budge, and I realize it's an issue with the coating.
So, exchange, or nah?
