It's probably not a super lesser. On outback reptiles website, they state that she was sold the them as a super lesser, indicating that they don't know what she is.
When in doubt, ask the seller to subject their leucistics to black light testing. Super Lessers and 100% white pieds will have no visible pattern under blacklight.
That's interesting, do you know if ivorys show pattern under blacklight? With the yellow dorsal and what looks to be black eyes, I would of guessed it was an ivory.
