I would not be surprised if start to appear diluted colors in CzW as weird characteristics due mutations, principally when it comes from a consanguineous mate, but show a different feature in a tipical dog, with tipical proportions is very different than show this in dogs we can see are not tipical.
Im nor even entering here in the merit of "someone cheated or not" but the fact that even by this simple photo we are able to see that these dogs are not CzW independant of their color, it's water clear by their heads.
