Gold hostas are either lutescent or viridescent to varying degrees. Lutescence only comes from sieboldiana/Tokudama genes. In all other species the gold ones are viridescent. Hybrids between lutescent and viridescent plants can be either. Which a seedling is is obvious from the first few leaves as with viridescent seedlings new leaves will be brighter than older leaves and vice versa for lutescent ones.
As long as plants are not bleached by the sun it will be clear in the garden. All golds and even some greens will bleach moving to bright yellow through a straw color before the leaf dies. Lutesence and vididescence seem to be the buildup and breakdown of Chlorophyll A & Chlorophyll B, while bleaching appears to bring out carotenoid pigments. No studies have been done to my knowledge to investigate that though.
Your list only has one plant that may have sieboldiana/Tokudama leaves - School Bus, which appears to be related to Purple Haze in some way. I've never seen the plant so can't say on whether it is lutescent or viridscent. All others obviously have no sieboldiana/Tokudama in them and will be viridescent to whatever degree.
Interestingly, I have seen pure gold sieboldiana plants that were viridescent, but they are very rare and none that I know of were named.
If you thought the auction was fun, come to the meeting!
