Incredibly difficult to tell from this picture however with what you’ve shown and noticed on the panel, a ballpark guess would be that two spots on the top fold of the door have been resprayed.
Strange if you’ve had it from new however damage can occur in the factory or at the dealership and are patched before hitting the lot.
To elaborate, those two patches look dark perhaps because there is a slight difference in colour and or metallic flake. Silver is one of the most difficult colours to match.
It looks as if two pieces of damage or unacceptable blemishes have been repaired and painted from the top of the sill to the first fold.
What makes me question my own theory is if two spots has been repaired, they would most likely spray the whole top fold of the door.
It may have been done by a quick repair guy at a dealership.
Get some shots of the area in full sun and under a detailing 90+ CRI light. This will help show up any inconsistencies in the paintwork to help determine what the deal is.
