Well, yes and no...each sensor definitely gets unique data, but as far as it
being actual "grayscale" data, not really.  It's just like putting a
red/green/blue filter over your film camera, it may or may not "see" things.

Well....not really...it still has to interpolate the "average" intensity
across colored sensors...
