Importing Zbrush OBJ with vertex color / primVar

Hi There,
I would like to import in an OBJ with vertex color (Cd) from Zbrush, I understand how to use primvars, however during the OBJ import process Create doesnt seem to convert the OBJs vertex color into displayColor for use in materials using the pimVar_lookup_color.

Is this not support yet or am I doing something wrong, thanks.

FBX export from Zbrush into create works as expected with primVar display color.
