But Miraak's mask resembles Apocrypha very much and it looks much different then any other Dragon Priest mask. He probably lost his former mask (Which may have looked like Dukaan's and Ahzidal's) and Hermaeus Mora made a new one for him. Also, the reason why their masks are different is because they were from a different cult then the ones in Skyrim.
