They are probably the only one with a colony. This looks like a wild millepora and has probably shrunken in size as they started to frag it for sale. It will be years before any hobbyist has this coral to any appreciable colony size. There is a good chance that it just falls by the wayside like so many of the recent import-and-frag stuff has.
IMO, if you want a similar looking coral with proven lineage, then look at the ASD Rainbow Millepoar... it is just an orange millepora (no idea why they called it "rainbow").
As for their stock photo, look at the purple egg crate. You ever seen purple egg crate available for sale? This should give you an idea of what to expect from this coral.
