Originally the front luggage area was body colour, I know of a couple of specialists in the UK that started to paint that area black many years ago - one of them was attempting to say that’s how they came from the factory, it was just easier for them not to paint the body colour and get a good finish as they could go back later and paint that area black with textured paint and less prep work required.
I think the black works quite well though tbh, personal preference as with most things.
