TBH, very hard to claim based on your current incident. They can say is your carelessness that caused this issue happened. The best solution is buy a camera protector to cover up the area or leave it or buy a new iPhone to satisfy your OCD. When you bought this iPhone, first thing we need to do is on the spot check the fault for any cosmetic defects before accepting the phone since the product itself came with premium price tag.
