Here's the thing: the majority will have a minor problem. Between yellow-ish corners, dust specks and dead pixels (biggest offender), BLB, and etc. - it takes a bit of perseverance to get one with no noticeable problems.
My 5th was a keeper. No dust pixels or dust specks, no yellow-ish whites, no yellow-ish blacks, very insignificant BLB and IPS glow that is significantly less noticeable than any other IPS monitor I've ever seen (particularly compared to my two previous Dell monitors). It'd be pretty difficult for you to argue that I can't see the flaws considering I've already went through multiple returns precisely for experiencing these flaws. Absolutely crushes any monitor in terms of the gaming experience it provides, easily. Even if it did have a stuck pixel in the corner - I'd still consider it way better than what I've seen from a ROG Swift.
I can easily imagine it for some people take more returns (which sounds like your case), and other people it takes less. Just how it is. I'd perfectly understand someone not having the patience to keep doing returns. There are keepers out there. Just not very easy to attain, unfortunately.
