You can definitely get this repaired. Probably a full wheel refurb though! This happened to me the other day, as well as some one denting my door. Not a good feeling hope you get it sorted!
On a BMW like this I don't like to keep battle scars, it's cool on old school E36's drift cars but not on a brand new 4 series thats nearly mintyea you can get curb rash fixed no worries, should just leave it, I call em battle scars
