Yes but when you clean them you don't need to use metal polish and get them absolutely perfect.
I had black chrome tips on my 550i and they were far less maintenance than the M5 ones.
That said your tips are painted not black chromed, so I don't know that affects the cleanability. I would imagine it makes it easier to clean since carbon probably doesn't bond as easily to paint as it does to metal.
