Greyish Circular Spot Visible on Black Screen Only with Flashlight

Hi, I recently noticed a small greyish circular mark on my MacBook screen. It is not visible during normal use, but when I shine a flashlight on the screen while it’s black, the spot becomes noticeable. I just got the screen replaced 2 days ago.

The spot doesn’t affect display performance.

Light wiping with a microfiber cloth hasn’t removed it.

It looks slightly greenish under the light.

Has anyone experienced something similar? Could this be a screen defect, residue, or something else? Any suggestions on whether it’s safe to ignore or if I should contact Apple support?
