[SOLVED] Half dead subpixel or dirt?

[gogi]

I could swear that there was nothing the first few days but this had appeared after a day or so of use.

In any case the monitor is brand new (Acer Predator XB271HA), and this is driving me crazy

Any suggestions with it could be and if it's fixable?

I've tried the suction cup technique with no luck, not sure if I'm just being too gentle, but it does seem as if its deep inside and not on the front layer, almost looks as if its part of the pixel mesh

Looks like debris or dirt caught between the diffuser sheets of the backlight. It's theoretically fixable, but would cost more than a new monitor. Just return and exchange it. If you try to fix it yourself outside of a clean room, you're likely to just end up with more dust and debris trapped inside.
