I think the differnce is horses do not "breed true" when it comes to color masking genes. I still would definately discount the double dilutes because the color is still expressed and showing, it has just been diluted twice and not actually covered to pure white/absense of color..make sense? (cremello and perlino diluting chestnet or black/bay...the color is clearly seen, just dilute)
IMO the closest thing horses have to albino would be a maximum overo horse. Even then, patchy color comes out most of the time. Seldom is the horse all white. It will never breed true however and most maximum horses either A. die of LWS or B. have colord ear spots or some such.
JMO of course...Im not a genetisict..Just find color intrieging.
