Some roses might have a long pre-introduction life. I mean, even if one planned to distribute a rose broadly it could take a few seasons to build up stock. One might take a photo before the plant is registered or introduced commercially. Or maybe Ruby Voodoo in the HMF files is a completely different plant from the one at Plant Select. This seems likely to me.
It's a little difficult for me to believe the Plant Select photo above depicts a rose with a parentage of General Jacqueminot x Stephen's Purple because the rose shown is a cluster-flowered rose that seems at least a little shrubby to me. Neither parent has either inclination: both are leggy and not very well branched; neither bears clusters of flowers. The color seems possible, but not likely. I'd expect flowers more in a dark crimson than a bright magenta.
