Well, looking at the mom, she is not a granite.

The dad is a lesser platinum.

He has some granitish markings, but I never noticed because he's a lesser, and also has a few larger spots.
Here is another baby from the same clutch:
This lesser has a lot of granite markings on him, very noticeable--more than dad, but he also has a spot or two.
Do you suppose the dad is a granite with some spots, and these little ones are better examples of the type?
The presence of these granite markings in the other hatchlings leads me to believe this is much less likely to be random. But this lesser does not have the broken neck stripe--his normal sibling granite does.
