Purple tint on my camera

Hi i got issue about the camera, when im in camera application with 0.5x or 1x zoom all the view is purple like it have something wrong with my cameras. I've searched how to fix it and it showed me the issue is caused by bad heat insulation of the camera sensor from the rest of the phone.

I have to return this phone to the apple store?

or i can walk-in to the store and told them my issue because i already have limited warranty, it expired on October 2022
