No, POV-Ray supports NURBS as much as most other renderers support them 
- by rendering meshes generated from them.  It is possible to directly 
raytrace NURBS of course but that is rarely done.  See also my general 
remark concerning 'does POV-Ray support xxx' questions.

No.  No algorithm commonly used to directly raytrace NURBS would allow 
displacement mapping.  So the above statement does not make sense.
