I think it's a yellow face opaline clearflight pied. The markings are unusual. I would have said recessive pied except for the flight feathers. Some breeding history or breeding results are needed to be sure of the mutation
Does this bird have iris rings? Recessive pieds don't have iris rings. Also what does the birds belly look like? Does it have a blue spot or is it solid. A recessive pied would have a spot. It may just be a mix of recessive pied and clear flight pied.
