Paint coming off iPhone

New IPhone 14 pro - $1600 and - put into case and screen protector as soon as purchased ! 5 months later the edges look like crap - paints chipped away around the edges ! Definitely low quality from Apple as I’ve not dropped the phone once ! And I’m all my years of phones, they normally look brand new after years as I mother my phones. Apple will deny its an issue and blame user.. very disappointing- has anyone tried paint touch up ? And ideas or links to paints etc ? My Apple Watch has a tiny paint damaged area - I use a permanent marker - looks great but rubs off in a few weeks ..,
