While vampires surely aren't ghosts, Etherealness also denotes the fact that vampires are usually impervious to normal weapons, which is essentially what etherealness does. While the name might be wrong, the effect is right. If you shoot a vampire with a normal gun, he is unfazed by it. In dom3, he would be dead but back in a month, which seems contrary to most vampire lore, where magic weapons harm them normally but normal weapons rarely do much unless used in a ritualistic manner(cut the head off or stake the heart).
