Gap between display and aluminium bezel

Hi!

Purchased an iPhone 12 last Friday and although it is amazing I noticed a flaw that definitely shouldn't be this way. At the top side of the phone there is a gap between the screen and the bezel, you can even see some of the internals and after one day dust is already getting stuck in the gap. I cannot imagine this phone is waterproof. Is there anyone else with this issue? In the Apple Store they told me this is just "cosmetic" so nothing they can do...
