Aftereffects of changing iPhone screens

Hey guys so basically my situation is that I have an iphone 14 pro max and I'm going to change the display (replace) to oem but pulled from another phone and also the proximity sensor too (yes I lost the original) and I was wondering if I will have any issues with dimming screen. I already know about true tone functionality being gone but I don't mind, are there any more problems I'm gonna face? (I really hope the screen dimming won't be a problem)
