After following the link and inspecting the photos what I believe you are seeing here is legitimate variegation of a type we in the gesneriad world call leaf chimerism. The meristematic tissue is composed of two different cell types and they grow together to create this beautiful display. It occurs in random mutation among propagation of offspring by leaves for African Violets (or rarely by natural occurrence in seed germination) but is generally stable. It would however only be propagable by offshoot, so Tissue Culture on this one is questionable. She sure is a beauty. If you want to try for this type of variegated beauty I suggest trying leaf pulls on some different heliamphora's. With less chlorophyll you will likely need to have high light, but at the same time will need to watch that the white more delicate foliage does not burn. I wish it didn't cost 1000 Euro.....
I would want to grow this plant in extremely stable conditions until I had a couple offshoots before I started to experiment with it in different growing conditions. Unfortunately for hybridizing the central colour of chimeras is generally what makes up the reproductive structures, so all offspring would likely be green. More of a Genetic anomaly than a breedable variegated trait.
Just one example of this variegation type in African Violets
I myself grow some chimeras and I just keep 2 copies. I also propagate it to distribute so that should the inevitable happen and I lose both plants there are others out there who will return the favour!
