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.

  That's not the problem with it. And it looks brighter because the sphere
has a non-black color (specifically rgb <1,.8,.6>).

  That's how it should be. It's very close to the sphere and thus minimally
blurred.
  Blurred reflection means that objects which are closer are blurred less
than objects that are farther away.
