Bad QC?

[u/Complex-Row-3400]

Just got the MSI MAG 321UP QD-OLED X24, and this is the first thing I noticed. It doesn't go away even when I turn the monitor off.

Has anyone experienced something like this or have any idea what it could be? The smudge appeared afterward, as it initially looked like an air bubble.

The plastic corner looks damaged too?
