I know this because it took me a day to figure out how to enable the setting on my bluray and hd-dvr box.
I was able to dial it out with just the brightness controls before I got into the hdmi settings.
On the owner's thread Scholar79 says he sees it on component, and that he had to go to below 30 on brightness to make it disappear, and that was too low. That probably matched my experience. The more interesting thing was that he also says:
If I am watching something 4:3 material with black bars on the side, they are definitely black and not gray; if there are black bars on the top and bottom, they are uniform throughout the length of the screen; if the picture is black (between scenes or what not), it is solidly black. You can, however, see them distinctly when there is a solid or almost solid darkish color on the screen (like the Comcast info grid, for instance).
I saw the bars on black between scenes. However, I don't recall seeing any increased brightness on the edges with normal full screen pictures, and I looked hard. I don't know what I would have seen on a starwars type space with stars image. It could be a software/image processing issue of some type. I'm particularly interested in this comment:

This should be easy to test - just feed a 2.35 aspect ratio movie to the screen. I would expect to easily see the side brightness nonuniformity in those upper and lower horizontal black bars if it's really a brightness/mura/screen illumination issue.
I also wonder if this issue varies a lot between sets. I don't think the set I played with (did not adjust gammma) could make the brightness problem disappear with a brightness only adjustment until the brightness was unacceptably low.
