on closer inspection (on computer and not phone now) I agree I'd just clean it up. i once had the same frame, same color, and the paint is very thin... on purpose so that the chrome beneath gives in a luminous sheen. that would be very hard to replicate with touch ups- and the chips and damage don't look bad once the whole thing is shining.
