I've got one of the -02s in my oldest c64 and this one actually fills 
the color ram, but by the current value of the background color (the vic 
register), not the "cursor color" (found in $0286). If you meant this 
difference, then (as I know from experience... back then, I even 
replaced the kernal by an eprom with the image of a newer kernal 
version, because of this small but important "bug" :-/ ) even -02 is 
like that... Or, does -01 the screen clearing by a third way, not 
touching the color ram at all?...
