I think he's a good animal for selective breeding, but I don't believe he's a morph. But who knows? Plug him into some morphs and see what happens. I suspect he would contribute a brightness to them. I selected normal females with very specific traits just for selective breeding purposes.
Anything genetic would be a morph. Some may not have much of an impact on other morphs but if it can be passed on to offspring it's genetic/morph. IMO.
