What morph is he?
 

Hello, I am very curious what morph my leopard gecko is. Can you please assist me on what morph he really is? I believe he is rare, for I have done my research and cannot find an exact morph. I think he is either a Black Night, Mack Snow Melanistic, Mack Snow Black Pearl or even possible Melanistic het Murphy. Here are some pictures I was able to take of him

Looks wild type to me, but I haven't really paid attention to leopard geckos fo many years. I had several wild type geckos that looked just like that about 20 years ago.
