Kahl or sharp albino?

[LCSCALES]

Ok fellow herp friends, I've got a friend selling me an albino boa, he got it locally from a big reptile store but was not told if kahl or sharp strain, I've got a couple pics you guys can see and let me know what you think…
Thanks.

I'd say Kahl, Sharp generally has more contrast as adults.
