Pretty sure its for the console not by gamer tag. Although i do not have an answer as to why you haven't received your sparrow. Gl you are definitely entitled to your Legendary sparrow.

No. I won't get it. The legendary sparrow is tied to the account/gamertag which purchased the DLC. That means only the account that purchased the expansion pass will get the sparrow. I will be able to play the DLC though. All accounts on a console where one account has purchased the DLC will be able to access the in game content. My brother will get Tumbler sparrow, but not me. The irritating thing is, I play Destiny more than him.
