Eh ? that definitely looks like it came out of the spray booth like that from new, slight pressure drop on the robot arm perhaps ? The 'plastic bit's' are normally sprayed separately from the metal bits...different types of paint.
Yep. I can't see how over-spray would have got there anyway in your ownership anyway so it is most likely a defect in the paint process before it left the factory.
If you can get to the back of it you will probably see that the part is originally black. if so there might be loads of black ones out there with the same 'problem' but no one has spotted it
