clearflight and dominant pied are two different types of pied, it is not common for a bird to have both and they would have a lot of white on them. he looks like a clearflight in the pic.
i think you are right about the mauve, he does not look right for a cobalt and greywing lightens the body colour a bit. greywing also makes the wing markings grey rather than black, are his markings grey - they look it in the pic but they can be different in reality....
and i am confident about him also being golden face.
