As somebody who has OCD, I have a similar condition RS1i (near-new) and I'm honestly not bothered by it, mainly due to the fact that if I did own a perfect RS1i, I would
constantly be worrying about it being damaged or looking for minor cosmetic flaws.
In my case, in the inner part in one of the cups, it seems as though the black paint for the grill overflowed onto the cup by a few drops. As a result it gives off this weird optical illusion that a termite bored holes in the cup.
