Question Black spot on display. Dead pixel?

[TACTI]

So I've had this screen for 5 months now, its an Acer XZ321QU 1440p 144Hz monitor, suddenly after a gaming sesion a black spot and hue appeared. I doesnt look like a dead pixel, since it gets covered when I drag something over it, what could it be, and could it be fixed?

Heres a link on Imgur of how it looks like:

Does it disappear when covered? Or is it just reduced heavily?

When you drag something of a lighter colour, does the issue persist?

Initially I thought it was something behind the 'glass' aspect - I've seen a dead ant, for example. Early in the imgur link it looks like it's still there, just (mostly) hidden.... but later it appears to be completely gone, so I'm not sure.

It gets completly covered, no matter the color. I have read that too, but due to the location of the spot, it just seems unlikely.

This pixel seems to freeze. Try another colors and little push on him.
