Just because you can’t see them easily doesn’t mean they aren’t a problem. Enough pressure on the back of the screen to cause bumps like that could cause issues with the screen. I’d definitely send that back. Luckily mine has no issue and based on the 12 Pixel 8 phones I’ve seen (including mine, a co-worker’s and phones in stores) and all the owner comments I’ve read it does seem to be rare to have those bumps.

Many Apple Watches have these „bumps“ as well. I really don’t see the the issue at all.
