I didn't say, you would get or at least see it. ;)

As said, the helmet exists in the original base game files. It was put to use with the original expansion, Tales of the Sword Coast, where the Demon Knight is wearing it, but only during the encounter in the tower's entrance hall. In the later fight, he's wearing another, undroppable helmet (which is changed in the Enhanced Edition).
