I have an 08 black mica, same thing...not all over the car but localized on the right hand back ...sad...but after a few weeks I forgot about it - until you reminded me(eek2)
Anyways, I had an Accord before, it was black but not mica, and after a bumper bender the body shop didn't paint the bumper right and I had them re-do it. They said they just "buffed it out"..
Maybe your dealer can do the same ?
Try, whine, complain, and don't let it get to you..Enjoy the real virtues of this marvel.
I know, we black owners are picky, but those first nicks and scratches will be more painful.
