GOLF 7 really a factory repainting?

Hello dear forum community, I am new here and find your forum really great ๐Ÿ™‚ I have the following problem, I have acquired a GOLF 7 BJ 2016 (In reflexsilber metallic) as a former VW factory member vehicle. After I picked up the car, I noticed repainted places on the fixing screws of the bonnet. I then drove to the DEKRA and the examiner found that the car was completely painted on the right, the roof and the bonnet. The roof and the right side partly up to 250 micrometers and the bonnet up to 350 micrometers. When I confronted the VW dealer with this, he assured me that nothing was noted in the vehicle history about repainted pre-damages. He explained to me that the cars are already repainted in the factory, but this is not documented and the bonnet may only have been re-adjusted. My questions to you: -Has VW possibly another “act” about the history wรค during production (according to the VW hotline there is no such thing)? If yes, do I have to hire a lawyer to view this file? -Does a VW really leave the factory in such a condition (fixing screws see pictures)? My problem is that if I want to sell the car, don’t want to hide it and I would like to have written confirmation from VW that the car was repainted at the factory. Otherwise it will certainly become more difficult to sell the car later….
