Even if some paint "chips" occur under the film and are removed/become visible when the film is removed, I assume those are spots that would have chipped off if the area wasn't covered in film. At least with film, any damage would remain invisible for the life of the film, which is usually many years, and you can go without having to constantly touch areas up. But like people here have already said, when the film is removed correctly, it shouldn't be an issue anyway.
