I am NOT good at this, and this is purely out of curiosity more than an opinion, but...
That particualr snake doesn't appear to be hypo to me. There is still too much black, as far as I can tell. BUT, I have heard rumours that some reverse okeetee lines MAY have been bred with creamsicles to help achieve that extreme high white saddle border.
With that said, and looking at your photo, that snake does not look to have "typical" corn coloration, even given the large degree of variability within the morph "classic".
Combining those two ideas, I am forced to question the purity of that snake. It COULD be a possibility that what you saw in the store was a clutch of creamsicles and rootbeers, rather than "true" reverse okeetees and classics.
I am NOT calling your snake a hybrid. I fully and complete admit that I have only a semblence of a clue as to what I am talking about, and I mean, really...VERY little information. BUT, with all the discussions recently, I am forced to ask the question of myself, and therefor I am posing it to you for your consideration. Do with it what you will...
