Indeed, but it appears that it is something more than just pale dots. As a parent it dilutes the color of the other flower in hybrids, hence the name of 'dilute' types. There were quite a few wild plants of that type that appeared about 10-15 years ago. Most had plain green leaves, like a bellatulum album, but a few had reddish leaves however.
They would be worth of a description as a forma, or possibly even a variety, as they came clearly as a colony, back then. They were not individual plants, as an albino would be.
