Is that displacement on object/sphere/plane/mesh or is is only on meshes (if
you know what I mean in my question)?

Thinking that way displacement of mesh surface is only new mesh (even if it is
calculated on the fly). You can work with displacement on
functions/isosurfaces were efficient way if you have tools like:
