Effaceable/Removable Smudge or Stain on Display noticed during unboxing

[emraha06]

As you know after removing the protective paper adhered on display some of us intently look for screen for a factory defect.
At this point, i have detected an isolated little smudge on m1 MacBook Pro 16” and cleaned it with cloth.

Has anyone experienced sth like this?

I will be greatful if you share your experience

Thanks

My second 14" (the first one's space bar leaving marks on the display) had some stain next to the notch. It was removed easily by applying a small strip of scotch tape. I did not find it as annoying as the keyboard mark issue.
