Starting from the closed beta and up to the demo version 0.8 (demo 0.9 is essentially the official release – it contains a couple of maps, and Campaigns are either missing or there are only a couple of maps from a Campaign), it had exactly this icon, but the texture is already from the official release, and in the aforementioned alpha, it doesn't seem to be present (I don't remember for sure). Ask footman; I just can't check right now whether that vampire was there!
By the way, I made the Beta Necropolis mod, and the higher vampire was created based on a screenshot from the game.
