I think I know what you mean...I also have what is theoretically 'Enchantment', but it lacks the black spots that it's apparently supposed to have.
The attached site lists the various lily selections and species, and the characteristics as registered.

Here is a link that might be useful: Lily Registry

Well, I have that problem solved. Sending the bulbs to the lily society and someone is going to grow the three enchantments we have here. They also have an original so after exchanging many photos we decided climate, soil and so forth make a difference so best to send the bulbs and see if they can be identified as to who the real enchantment is.
