Honestly, many breeding records are bogus... I had access to some Phalaenopsis real breeding books, including in Taiwan, and we see things like 'Cut flower Mr.XXXXXX' as the origin of a plant with a parent number. Later, that parent number was registered by the RHS with bogus parents and a nice name, and it is a very, very famous one. The competing nursery eventually got as well cut flowers from Europe, and did the same thing. To say that both NoID are some of the most famous white phals in the world is an understatement...
You have that as well:

Which pedigree do you prefer for the same plant, after all ? They were both submitted for a PBR to use as mass pot plant varieties, and turned out that they are the absolute same variety...
The TRUE origin of the plant was mass cloning of a pure pink variety, that turned out to produce that mutation, a bit like the Big Lip or Harlequins single ancestors...
Complex paphs, the spotted ones, the leading breeder of them is in Germany since a very long time, but for pot plant... So for about 20 years, people have been fed Complex paphs in Japan and the USA, even some of them got awards, some are offered for few thousands dollars in Japan, but they are all complex NoID. The parentage is done as 'well it looks a bit like this times that, let's put it and register it'.
I saw a batch leaving to Japan in January this year as an example... and let's say I saw the plants and flowers photos at the Tokyo Dome, but they were not anymore Complex pot plants for Lidl. There were both spotted and white complex paphs.
As for the roths, I like the Sunlight Sky Roths a lot, I have to say. Some are absolutely gorgeous, there is no doubt, and they would have the same financial value to me as a roth...
A chihuahua x rottweiler would not be judged as either, as a fact... On the genetics problem and that it just incorporates some genes, I don't think so at all. It incorporates clusters from the other species, on one side. Plus, the mother plant transmits the mitochondrial DNA 100%, there is no 'breeding' there.
So if these Sunlight Sky Roths used stonei, then the hybrid as parents, as motherplants, they have full blown stonei mitochondrial DNA, none of roth. They cannot be used to reintroduce the species, eventually they will wipe out the real species in cultivation ( real paph primulinum has not been collected since at least 40 years... and there should be less than 5 people who have the real one in the world, completely different from the Pinnochio yellow sold by the Orchid Zone as primulinum 4n, that did spread worldwide...), and losing some gene pool.
At a point it is cheating, at least on the hobby market.
For the commercial Cymbidium, Phalaenopsis varieties, we never, ever release the exact pedigree ( no need to help the competition), so you have Anthura Narbonne, Anthura Montpellier, etc... In those, using NoID or a lot of weird parents is OK. Not if people sells something as the real species and guarantee they are 'pure' roths...
