I am trying to understand what these two modes of interior lighting are. There are two options for "Sport Mode" and "Classic Mode".

I would have expected it to be on or around page 91 in the owner's manual. In the lighting menu on iDrive the option I am referring to is directly above the word "ambient" in the picture below. I suppose sport and classic could be pre-sets for the brightness of the ambient lighting but if it is I couldnt discern a difference.

Anyone have any idea what this could be? I will take a picture of the actual menu from my car in a bit.
