Repainting the new vehicle – paint density?

Hello! Have an important question. My new car is at the dealer’s, but this one knows some paint damage and even a paint inclusion (see appendix). Now the dealer (or Renault itself) offers as a solution “only” a repainting (guarantee) of the affected places. That would be 2 fenders, bonnet, tail flap – so soon the half car. But the seller said it was better not to do it, because then the paint density (when repainting) would change and that could be measured . Is that true? A friend thinks: NO, ass. Only when spatling changes that. If something is repainted this is not an issue. The vehicle is as said NEW (!) Similar to this:http://www.motor-talk.de/…/…rn-or-repair-require-t4771627.html
