As I was reading through this thread I was thinking the same thing, I bet both are het for Ultramel and what you have there is an Ultramel (+ het for Lavender Albino). The pattern looks exactly like Ultramel and from what I've seen the colors can vary quite a bit in different lines of Ultramel.
This kind of reminds me of the Monarch project, the guy who discovered it popped out an unexpected snake that looks similar to this and named it 'Monarch', but I'm starting to wonder if was actually an Ultramel too. I'd be really interested to see someone cross a Monarch with an Ultramel to see if they are compatible. Speaking of which, a good way to prove out this guy would be to buy an Ultramel, pair them up and see if you get visual Ultramels or if you get normal double hets. I'd say if it's not compatible with Ultramel you may have something new here and it could be significant. If you could get your hands on a Monarch that would be an interesting pair as well...
