Then it would be classified incorrectly, an inc-dom morph just needs a intermediate heterozygous form, doesn't matter how subtle. A recessive wouldn't have a marker if it is truly recessive.... yea we already have enough misclassified genes. As for disco they are a few shades lighter than a normal ball python, hardly need experience to see that. and red axanthics are inc-dom, not many people will argue that. het red axanthic is very visual.
As for this morph the thing is quite a few shades lighter than a normal, I wouldn't call it desert. The color is might be similar but lacks the cleanliness of the desert which is it's most sought-after trait for most. I don't see it being a game changer right now, but they probably said the same thing about the orange dream. Good luck with the project.
