I don't think that would be possible, due to the fact that there is nothing underneath the polygons representing patterned sections. There's no way for the renderer to know if a given polygon represents paint over top of the part's inherent color, or something else. There's also no way for it to know the opacity of the paint, which I am sure differs both based on the paint's color and based on the part's age. (I can't imagine that LEGO would avoid changing their paint formulation if they knew that a new formulation would be better. I assume that it has changed over the years.)
