Wow that’s like a chunk missing from the frame. When I looked at your sixth picture, I thought you were referring to the mark in the stainless toward the top until I realized the circle. It’s unfortunately the reality of this 13 series so you have to pick your poison. If it were on the side of the stainless the decision would probably be easier since it would likely be covered with a case. This is looking right at you. Me personally would return it but I don’t tolerate the physical damage well. You have to weigh what would bother you more since it sounds like your screen is on par with your liking. When (if) it comes to resale, people will notice chips and scratches more often then screen imperfections which are more visible with certain color images at the lowest possible settings. Not everyone has an eye for it.After 5 swaps, eventually i got a decent screen. Beautiful white and uniform. Some picture of my new (five) vs old (4th swap).
There something that bugs me: a very tiny chip on the metal frame.
What would you do?
I think i'd keep this one.
