SITF confirms this plant as Dossinia marmorata (C. Morren) (May 2024) without a type (form) designation. There is no taxonomic standing for the putative "Dayii" form. The leaves are not as dark green, but more olive. There are fewer reticulations and they are pinkish rather than silver. This is a classic form of D. marmorata, as illustrated in photos of the plant and flowers in the IOSPE. There are also 17 images of Dossinia marmorata in the orchidroots.com that match this plant in both leaves and flowers.
