No, I don't think it's Pied, because the head stripes are pretty wide across the head. But... watch the feathers as the wing feather start coming in, if the first few flight feathers are pure white (at the very tip of the wings) then there's a chance it is Pied. Next step would be to watch for white chest feathers as it feathers out even more.

Chocolates have white wings all the way to the shoulder and white on the side of the face, as well as white chest and belly...until they start feathering out (very similar to Royal Purple keets).
