iPhone 13 Pro yellow screen after latest iOS update

My screen turn yellow after updating to the latest IOS. When it first started, the screen was able to return to normal hence I was able to backup my phone into my PC. Went down to apple store and the first thing they said was that it could be an hardware issue hence causing my screen to turn yellow. THIS IS NOT TRUE! Thank God my screen return to normal for a moment and the staff was able to help me reformat the phone. Phone was doing fine through out the day until I went back home to restore the backup to my phone and the screen turn yellow immediately. Hence, i can conclude that it is definitely a software issue which apple is not resolving and insisting users to change screen. So they earn $422 out of every user who faces this issue. So now my problem is what if I am willing to pay $422 for the sake of all my precious photos of my child. What if after restoring the backup from my PC my screen turn yellow again? What can I do? Please advise as I don't wish to lose all my photos. Those photos are not stored in icloud.
