I find the whole species and judging to be a bit subjective. I know my opinion on this is different from many well-respected growers and judges.
The two main sources of genetic variation in a species are mutation and recombination. If through the process of selection, a mutation for a particular trait is defined, how is it different if the source of that trait came from another species and was introgressed via recombination?
As a breeder, if I cross a bell pepper (Capsicum annuum) with a wild species to introgress a single gene of tobamomosiac virus resistance and then backcross back to bell pepper to gain the main agronomy traits of bell peppers, we still call that new line Capsicum annuum. Why would this be any different with orchids?
I know many disagree with me, but that's just my opinion.
