It's clearly charlesworthii x venustum.
Regarding the colors, either or both parents could have been half or quarter (or even further "diluted") album rather than pure album.
I believe this is rather common since there are not whole lot of album populations and breeders mix the colored forms with album in order to creat more vigorous (or otherwise desirable) album progenies down the road.
I have bloomed one seedling of charlesworthii album x green complex.
The plant had quite a bit of purple pigmentation near the base, so I didn't have high hope that I would have a giant charlesworthii album like flower. When the spike came out, itwas indeed very dark with dark hairs.
The flower had quite a bit of pink shade, like a pale version of King Charles.
I now have a second seedling of the same corss in bud.
This plant also has purple pigmentation at its base and the spike is dark.
The bud is showing a lot of pink. I think I'm going to toss it unless it has a very nice shape.
I believe that either the charlesworthii parent was not a pure album or the green complex parent brought up its color genes.
I would think the former is more likely.
