Reduced doesn't mean less side pattern, it means over all reduced pattern. Your spider has much pattern on the top half of it's body. That spider I showed you is about as reduced as they come, probably the absolute best example of a reduced spider.
What you are referring to is a barbwire back spider. The pattern looks like a barbwire strip running along the spine with no real patterns on it's sides.
As well as there is no such thing as a "genetic banded" spider. If so that would include bands that wrap around the spiders body horizontally, which yours doesn't have.
