That might have been one of my posts, since I observed that trait in my last grow out. The flavor of the all-black beans was noticeably sweeter (IMO) than the black & purple beans.
IWK originally appeared to be a land race, but the ease with which the colors can be separated (or eliminated) has been frequently mentioned by those who have grown it. Believing the white beans to be the result of a recent cross, I planted only the black or purple beans - and eliminated the white-seeded variant in one generation. Chances are that the all-black could be isolated too, but I don't know how different that would be from existing black-seeded cultivars such as Black Knight or Black Coat... and IWK (even without the white) has exceptional vigor.
Not sure if user Fusion_power posts here, but he has stated his belief that IWK is more of a mixture than a land race, and that does appear to be possible.
