If referencing the red-purple blush in the leaves, that can come from a huge number of sources. laueana, emarginata influence, rotundiflora, some moranensis and agnata clones, will all pass on red leaf color, so that won't narrow it down. If it were a cyclosecta hybrid, the flower would be more purple, and it would be a very distinctive purple shade in the leaves different from what I see there.
