Remember, yunnanensis is one of the smaller ssps, ave. about 150 cm. Friesi is the largest ssp. Yunnanensis is a montane form, as far as I know, and I've even heard there's a dwarf morph which is the smallest taeniura, yet.
I think all the ssps. are variable. For instance, t. taeniura has a green morph and a brown morph. Also, the patterns are somewhat variable. Because of the possibility of crossing the different ssps, we'll probably have to resort to scale counts, and other more technical characteristics, in the future, to be sure of the ssp. that we actually have.
Folks who have specimens that have classic color/pattern, the correct size adults, and within limits on the scalation, will have the primo snakes to sell. For instance, check out Colubridman's photos of the blue beauty for awesome snakes.

>>Good question & one that I'd like to know the answer to as I've got a young female that looks very similar (see photo with some young Blues). Certainly the neck pattern & tongue colours are Friesi but her colouration looks more Yunnanensis.
