Park scratcher with paint!

Hi I noticed today, that I have a scratch with opponent car paint on my driver’s door side about 2-3cm long. The color (blue) is still super good to recognize. That is certainly a door-park-rempler scratcher, who lives with me here in the residential area. I have already checked in the surroundings if anyone can stick my paint on their door. Unfortunately in vain My question is now… Could my insurance look at the damage and the paint color of the corresponding vehicle find out? Then the search is also easier. I still have partikasko, but is canceled in July and then I drive only with liability. I am very grateful for every helpful answer
