Unfortunately iPhone cameras are garbage for the past like, 5 years now. The processing like you mentioned is way too aggressive, but also, the focal distance is way too far to get good photos of anything up close unless you use macro mode which can make things look kind of wonky in my experience. I had an Xs and got the 14 pro last October and it’s funny because the main selling feature besides dynamic island is the cameras, but in actual use, they suck and are worse than my Xs. Honestly my iPhone 7 camera was fine.
