Faint circle on the back of my new iPhone 16 Pro

Probably a dumb question, but I just got a new iPhone 16 pro yesterday and only charged it in the apple store on one of their MagSafe chargers while my phone was downloading a backup. When I got home I noticed a faint circle on the back of my phone around the apple logo. Is this expected to be visible? Worried that the MagSafe charger did damage to the phone or something. Thanks!
