Clematis: My only flower bud and bloom on Ville de Leon, 0 by CountryGrl

Years ago I bought a clematis, but didn't know what it was. I planted it out back but it never did much. Last year I moved it up closer to the deck to see if it would do ok there. I have a Prince Charles a few feet from it that just loves the old clothes line pole so thought maybe that was a better area. From what I can tell, it is a Ville de Lyon but the flowers are fairly small. I'm hoping that it just needs to adjust to its new surroundings and will fill out more in the next few years. My question: Is this really what I think it is? If so, I have another one out back that looks just like it.
