There is a key in understanding this: input dynamic range. You will see VERY visibly better photographs shot at lower ISO and as there are plenty of them, there is no need to show one here.

But all of them must be of the kind where a large input dynamic range (larger than that at a higher ISO setting would allow you to capture) is compressed into the lower output dynamic range of a JPG or your display.

In practice, this means that shadow regions only have increased brightness in post.

If entire images have increased brightness in post then there will be no visible advantage in shooting low ISO (except where a post processor like LR5 includes a highlight preservation algorithm when adjusting exposure).

Once one understands this simple fact, there will be no reason for asking the question anymore.
