Strange marks on brand new iMac 24 M1

I have just bought a brand new iMac 24 M1, then 5 days later while the screen is off i have noticed some few dusts on it, so i used my iPhone flash light on the screen to check it, then i have noticed some strange marks at least 4 marks arround the screen. i did some googling but couldn't find any clue apart from bubbles problem which is not what i have.

If you look at the photos it looks like some plastic layer or something, but it's not a bubble obviously so im not sure what is that.

PS: If i removed the flash light you can't see these marks at all but the dusts only.
