Is the Three-eyed Crow identity on the show the same as on the books?
As we know from the books, the Three-eyed Crow is actually
Ser Brynden "Bloodraven" Rivers, one of the Great Bastards of Aegon IV Targaryen; he is an albino, one of his red eyes was lost in battle and he has a large birthmark on his face.
I was puzzled by the absence of his distinctive physical features from the show depiction, he is just an old man here; I did a little search (it's been a while since I last watched those episodes), and apparently his former identity as in the books is never mentioned on the show.
Is there an official reason for this omission? Is it implied that his identity is the same as in the books, or is he meant to be someone else? Or, was it chosen not to attribute to him any particular identity to keep things simpler?
