“ Excellent
When something's been used a bit but is still close to new, you can file it under Excellent. For modern gear, Excellent items are almost entirely free of blemishes and other visual defects and have been played or used with the utmost care. For vintage items, there may be some marks here and there, but the item is still in the top echelon when compared to similar examples. All Excellent items should be 100% functional in every way.”
That description doesn’t matchup with the pictures you’ve posted.
That being said, personally, if a guitar sounds and plays amazingly I wouldn’t want to send it back. I think asking for some money back would be appropriate (not sure the right way to phrase it with the guy that would get him to feel that way) but be prepared for them to dig in and say “just send the guitar back” - if it plays and sounds as good as you’ve mentioned maybe it might not be worth the hassle.
Ultimately I’d take paying a bit more for a non-mint guitar that sounds and plays amazingly
