I guess, in this case you could also have used an ordinary 24 bit image, or
even 8 bit, for the clouds with the same result. I don't think HDR does
anything important here. You have "just" setup the scene better than Ib.

The darker reflections are from real objects, and the sky is bright so the
possible constrasts in HDR, isn't used.. If there IS a dark horisont in the
HDR image, you could probably easily replace it with a textured plane or a
little heightfield..
