No, mostly white Aussies will stay mostly white, and are usually the result of breeding two merle parents. Most of the time the mostly white pups (called pattern white) are bline or deaf, or both. If not totally blind, many have eye deformaties. Some are born totally without eyes.
The color genetics in Aussies are not the same as in heelers so don't follow the same pattern.
Even in colored Aussies, the markings don't change much. The copper or tan points will possibly get more rich or noticable, and white on faces may shrink some, but it doesn't totally go away.
