No, actually they're not. They're ordinary selections that you can find at many LFS's that deal in relatively high-end corals. And it's actually "Cornbred" if you wish to look him up on e-bay.
The listings are highly photoshopped to greatly increase saturation, and all are branded with catchy-sounding names. No coral will actually look like the pictures when it's in your tank.
And yes, if you're someone that's tempted by these sorts of listings, you may want to carefully examine your motivations for keeping a reef. Is it to have a coral to brag to your friends that you own and they don't? Or simply to enjoy what you have because it pleases you?
If it's the former, you're in good company. This behavior is quite common in all sorts of pursuits - classic cars, antique furniture, fine art, etc...
The best way to characterize it is: "The thrill of acquisition and the boredom of possession."
