I don't know how you can prove it was not captive bred other than knowing that population of kings very well and knowing its pattern type came from somewhere else, like a striped Cal king found well outside its range. With desert kings, I wouldn't have a clue.

I've heard there are two types of axanthic desert kings, visually at least. Some are born with white and others with a bluish white waxy color.

There's also a very light hypo type desert king in some zoo that may be a T positive albino. It looks very light brown unlike the typical hypo desert kings. There's actually a story behind that morph that is hard to remember. I think someone found one in Texas.
