It's very difficult to see in this photo but I can make out just the tiniest bit of side pattern in the lower part of the picture and I don't think it's a super stripe. May very well be super banana. A super stripe wouldn't have a well formed side pattern high and tight to the dorsal anywhere on the body though, even when the colors are difficult to make it out. Instead, the pattern would be sort of washed into speckled mush away from the dorsal. Depending what the guy is charging it may be worth the gamble, it may not be.
A super banana super stripe would look pretty similar though to what you are seeing in the poor photo without enough definition and light to see the side pattern.
Here is an example of someone's banana superstripe, and imagine that with less contrast between the colors and you have a super banana super stripe.
I definitely see what you mean. I was able to get a slightly better picture and I can now see more of a pattern. What do you think?
