I would think that unless you have a particularly steady handhold, you should see a difference in the VF at 500mm when using a slower shutter speed particularly.

Have you tried actually taking a few shots with it ? I would guess the easiest way would be to take a few shots (handheld) of a static subject with IS on at ±125th (or even 1/60th) and then repeat with IS turned off - then compare them - there should be a difference.
