iPhone express replacement question

I’m having a question on my express replacements.

I am on my third 11 promax now I noticed something with ear speaker grill and I want to confirm if it looks the same as yours ?

I did contact Apple Support spoke to a senior advisor they say it’s normal

I Wont set up Express’s replacement because the next one could have more problems and if this could be done at the store Once there open it will be quicker
