Have a look inside the shader and find what drives the displacement
noise, below in a gray network box if I'm not wrong. From there you can
always use P and transform it to world space with a Transform Vop and
plug that into the P plug of the noise. But I'm surprised that the rest
doesn't work, I would think that this shader has that built-in.
