My plant isn't in flower, so I can't post it in flower, but here are 2 pics of it's parents, which, as far as the flowers position/shape/color and cane type go, are the same (mine looks just like Okayama gold)

and the other is Den. Santana, which is about halfway down the page here

Being a nobile type, it blooms directly off the canes with 2-3 flowers per node, like the parents of this hybrid and is also yellow. It does not make a long spike with many flowers from near the top of the plant (the way a phal or antelope type does, the twisty petals on yours indicate it may have antelope ancestry).
Since these are the parents for the registered hybrid and are nobile types, it appears the nursery your's came from cannot use the name Fancy Yellow, since it's already in use and registered.
The grower may have planned to use the name Fancy Yellow and had not yet regsitered the hybrid, or may not have planned to.
Just wanted to let you know, as giving your plant nobile type care would probably not be good for it! Someone with orchidwiz would be able to give the actual breakdown on ancestry without having to trace back using RHS, which takes forever for some hybrids!
Either way your plant is beautiful!
