  You are right.

: applied to the sphere...

  Nope. The sphere is truely reflective and has just a
pigment { rgb <1,.8,.6> }

  And besides, an image map applied to the sphere whouldn't look like that
(unless it was an extremely cleverly calculated image map, which I myself
don't know how to do).
  However, you are getting closer...

The reflected image seems brighter.

The reflective sphere's shadow does not seem to be blurred in the
reflection. Is that it?

It shouldn't be, at least not very much compared to objects further from the
sphere.

Do you think it might work with scattering media?

I would say :
each blurred object has an alter-ego slightly bigger, but
nearly transparent, with no_image and no_shadow,
maybe with an IOR, at the same place as the object.

Just like adding a glass surface to the blured object ?

  I don't think so. You can only diminish the visibility of things with it,
not blur.

  In pov3.5? I don't think so.
