Is This Dead Pixel, Stuck Pixel Or Just Dust?

[blithe35]

Hi. I've newly purchased  Acer XB271HUA. But I realized something center of my screen. I thought that dead pixel and try to fix it via software and rubber and try to clean via isopropyl alcohol but it didnt worked. After I look closely, it doesnt seem like to dead pixel to me. Can you guys check photos below and tell me what are those and how can I fix?

Have you tried . . . cleaning it?

Looks like dirt between the backlight and LCD panel.

I know some people will say it's not a big deal, but If I had a dead pixel or dust behind the screen that was not removable, I would RMA the product.

Though, have you run your finger over it?  It could be sticky residue that won't come off with a light cleaning.

I tried to clean with isopropyl alcohol. Nothing changed.

They don't look completely dead but they're dimmer, it's a defect either way and shouldn't be accepted, it doesn't look like dust to me.
