I think the variability of Phal pulcherrima is only a half truth.
Besides having 2 very similarly looking sister species in Phal buysonniana and Phal regneriana, many better strains of Phal pulcherrima in fact have Phal equestris as an ancestor a number of generations back. Then, some plants have also been chemically treated to increase their chromosome count (from 2N to 4N).
This situation mirrors that in Vanda (i.e. Euanthe) sanderiana whereby so many hybrids that have Vanda tricolor var suavis or Vanda coerulea as a remote ancestor are now virtually indistinguishable from the true species plants, except for their heightened colour, freer flowering habit and longer inflorescences and greater vegetative vigour.

Disastrous situation for a diehard purist (i.e. species collector). I collect mainly Phalaenopsis, Paraphalaenopsis and Vanda species. Lack the space and money to collect the hybrids as well (although they can be very beautiful).

I got to know about the impurity of some Phal pulcherrima lookalike plants recently from an very experienced orchid species collector cum nursery orchid owner. He did not elaborate.
I guess certain tell tale signs to look out for are smaller than usual lateral lobes of the midlobe, errect-incurved lateral lobes of the midlobe, a lightly-arched column etc. In the end, I think only those very wild-looking (i.e. "wind-blown" small-sized flowers) are truely Phall pulcherrima.
Accordingly to Eric Christenson, the dorsal sepal should be about only 1.2cm for Phal pulcherrima (with callus very shallowly notched) and Phal regneriana (with a well-developed bifid callus), and 2.2cm for Phal buyssonniana.
