I believe Nothing is wrong with your phone. Nothing is good in my camera either. Just like so many have reported in the forum. Also I do not believe it is going to be fixed. Maybe Nothing has no good software people, because SONY hardware is normally very good. Have an old SONY almost 20 years old and this take better pictures than the 2023 Nothing 2 phone, also a cheaper Samsung A53 has far better resolution and more accurate colours.
All we can do is not buy more from Nothing. Unless a miracle should happen and Nothing come with an update that take care of the problems, which I doubt.
