If you compare the leaves on the blog I linked to above, put your photo next to this one, you can see the leaves of Just Joey are broader. If you can't see it, look close to the tip of the leaves, those on your rose have a gradual slant.
It's dark now so I can't take photos of mine but the one on the blog looks like a typical Just Joey. When you've been looking at small details for a few years you can spot these differences.
