This is a sibling cross of 2 select C. skinneri alba cultivars. This plant is well-established in a 3.5″ pot and is a year or 2 from blooming. While seedlings can vary, species seedling flowers tend to run pretty true, so I would expect the flowers to be pure white and quite similar to the photo shown.
Cattleya skinneri is an easy-to-grow Cattleya species that has been reclassified as a Guarianthe and it can be called either a Cattleya or a Guarianthe. To learn more about this species, see https://www.orchidspecies.com/catleyaskinnerii.htm.
