A skilled hand could definitely do it with a fine-tip pen or paint - plus there are creative approaches and materials that would not be permanent or could be carefully "removed". Black self-adhesive matte vinyl that is precision cut with a Cricut to a pinpoint dot will likely be my approach if I need to add it. Easy/safe to remove, but does the trick in the meantime visually.
But I just don't want to make any changes like that until I know if it's a batch error or a production decision in case they need further documentation.
As for a photo without the belt - I don't want to overhandle mine right now- but there is an IG/TikTok showing the body/TV piece unassembled without the belt on (at the 11 second mark):
