PRobably just a really nice normal,every single breeder has animals in their collection like it, unique animals that don't proove genetic. We have a very similar looking normal here.
Remember in the past some of the wildest looking balls proved not to be genetic.Ask Ralph Davies, BHB et al. This guy from BHB is a very good example of a snake that proved NOT to be genetic.
