PG259QN Pixel Error quota?

Hello fellow evil eye worshippers,

What are the chances to actually get a pixel error free PG259QN?

I've gotten my first order and was able to spot a red dot on the right bottom side and one at top corner.

My question now is whether I should send that one back and go for another one to try to get one without Pixel Errors or is it rather unlikely to find a flawless panel?
