The head is different than anything I've seen - but there are lots of different head patterns in Cal Kings.

As far as black tipping of the scales - my wild caught cal kings have scales that are tipped in the cream bands - not black, but then their base color isn't black. So it does happen in wild type cal kings, at least in northern california.
