My iphone 13 pro looks damaged after getting the battery replaced at an apple store

I got my battery replaced about 6 weeks ago and I just now noticed little imperfections on the edges of the front of the phone.

There are some spots on the stainless steel that looks rough and not smooth, like the stainless steel was damaged or the screen wasn’t put back perfectly. I tried my best to take pictures but it’s hard to get on camera

It’s only noticeable in certain angles and lighting so I don’t mind it too much but it is kinda annoying to think that my phone was damaged or that the screen wasn’t put back properly. I’m also worried that the waterproof seal might be compromised. Has anyone else experienced this?
