Another thread but in short, "het Pieds" have pretty reliable markers and affect other morphs as if they were actually inc-dom. Also, the Leopard thing just solidifies this as then now you have Leopard as well as the "het Pied" gene in the Pied complex. Therefore, IMO "het Pied" is a somewhat subtle inc-dom gene with the Super being Pied.
I am not the only person with this thought, and I did not originate the idea.
