Vizio 60" Black screen light uniformity issues?

Hope this is ok to post here as there are several retailer threads on the Vizio 60" and it was the big "get". I'm wondering if others with the Vizio experience the same black screen lighting issues that I'm seeing (and other SD'ers have reported). I'm coming from a plasma TV and the issue is that when the screen is black (when first turned on, bars when watching a blu-ray, etc), certain areas of the TV, mainly along the bottom, appear way lighter (especially the bottom left corner). Only during black is it really an issue, pure white and colors look great. It's noticeable and distracting when watching a blu-ray movie since the black bars are always there.

Some have said that's just what you get with edge-lit and many LCD/LED's but wanted to see if my unit is in line with others. I was using the CNET recommended settings and even tried turning the backlight down to 0 but still pretty much the same. Overall still a great deal at $700.

You can see how it is lighter along the bottom, especially the bottom left (the image may be rotated on certain mobile phones, in that case, look at the top right)
