It is a ornatissimum, a nice one, difference are non papillose sepals, striped dorsal and petals, different Palae and different lip, when you see the two side by side there is no mistaking: 90% of the roth photos I see are in truth ornatissimum or hybrid of the two, just go back to first descriptions and drawings and you will see whath i mean is just an error we put forward since many years,the two species can be very similar indeed at first glance, not always it depend on ornatissimum population the yellow /creamy type is less likely to be confused.
Another big mistake is plants of appendiculatum or putidum very often sold as ornatissimum, sometimes even hybrids are sold as such.
I have a photo comparison collage of the species done by my friend Roland Amsler, will post it so you can see better looking at these side by side
