I've been told,( but it could be mythology ) that the reason why the paint looks different on the plastic bumper than on the metal body is that when the paint is applied in the factory the paint cools at a different rate on the plastic bumpers than on the metal body. This is more apparent on metallic paint finishes as the different rate of cooling affects the appearance of the metallic particles in the paint.
As I said this could be rubbish , but there is a certain logic to it.
