Yes and no. Without getting complicated, the best answer I can give you is depends on the color. If its something like black, they can just paint the door and fender due to the hue of the color. Theres a slight chance your eyes can distinguish the value difference. Where as matching a white is shitty and almost, 9 out of 10 times, is blended out. It also boils down to skill of the painter and what the shop perfers. Mostly it lies in what color your dealing with.
