What do you expect from the forum now. An expert was on site and gave his assessment. He will have justified this to you professionally, won’t he? Or do you doubt the blunt competence or neutrality of the expert?

The expert was commissioned by the publisher and I find it strange that the stain should only be visible from inside the room. I can always see it from the hallway through the glass sliding door.
So he is of little relevance to you. If it bothers you and you can't get rid of it (we were able to remove smudges well with a fingernail), then you have to spend money on your own expert.
I am really fascinated by the industry. Marks left by permanent markers and glue residues are the norm. Then an expert is commissioned who determines that the stains cannot be seen from the room and therefore are not a defect. Funny if it weren't sad.
Imagine the hairdresser cuts your bangs 1 cm crooked and dyes your hair blonde instead of brown. The argument then is with a DIN standard and that the color can hardly be distinguished at dusk.
