Just Bought New MB Pro M4 16'' and the screen has tiny dot

Hi everyone, I just upgraded my old mb pro to a new M4 Pro 16'' 10 days ago and last 3 days I noticed there is a tiny little black dot at the screen I tried to clean with a special wipe but it didn't go. I brought it to the retail store they directed me to the apple store in my city (istanbul-zorlu avm) they gave me a paper and went back to retail store when I am at the retail store they said the paper not for re-new the product and they said its cosmetic.
