I agree with you that multiple wings might be something exclusive to the Lucifer bloodline.

Just a thought/guess: - If you think of it in this way that Lucifer was once an angel that fell from the heaven just like the usual story says, it would make sense for him and his bloodline to have multiple wings. And if you are wondering why the wings are not the same as the other fallen angels and just like the devils, he might just be a unique case being the first angel to fall and him being a really unique angel like Michael.

P.S - If I remember correctly, some call Lucifer the father of the devils. Kinda makes sense if Lilth is being seen as the mother of the devils.
