The price was only $80 which really is not much more than retail for a normal western. Maybe $10-20 more. In the bottom pic I do see the color difference or should I say shade. It definitely is lighter, has more blotches instead of bands. I would say it is definitely a nice looking hognose. Would I call it a morph? Well, the guy says it is and he has bred it to prove it is co-dom. If he is not lying. Ask for pics of the parents or others he produced. If he shows proof of their co-dom linage then I would tinker with it.
I have a Ball Python that reduces the black patterns but I do not call it a morph or such. I just call it a normal that has a nice pattern that can be passed on.
However, I do not agree with the pic on the top. That looks like a normal western.
