Well well well... Riddle me this, my Lux bretheren!

One of these things is not like the other, one of them is kinda the same.

Same scene, same mat settings. Even used the same EXR light data from a Vue image.

Only thing different was the Lux version! 

To get it working, I ended up pulling all the displacement maps out, and any additional Subdivision settings, in case anybody else runs into such a predicament. 

(Also found it interesting that the EXR gave nice shadows in RC2 but not RC4!)
