Aha, I didn't know that.

It sounds to me like a displacement pattern value will displace the surface
in a specific direction rather than displacing it in the direction of the
surface normal (or vnormalized gradient vector). That makes me think that it
is not useful for displacing a surface by a specific and detailed 3D solid
pattern. Is that correct? Maybe there's another method for handling this?
