People try to be helpful and I know this is a video forum not a photo forum, but many times people just don't understand how to take a picture of a TV.
You MUST turn off the flash. You must have the metering be on the center of the frame (or zoom in, until the TV fills the frame).
Looking at shots with a flash, tell you nothing about how the TV picture looks, unless you watch TV with a strobe light going.
Finally, if you want to see what a TV looks like, you really need to go see it (albeit many stores do not have them set up well, but it's still better than a 640x480 jpeg compressed flash shot) for discerning details.
To your specific question, to my human eye (I have the 67") there is no perceptable brightness fall off in the corners.
In the picture you reference there is a flash. Behind the the whole screen is one GIANT mirror (though, of course, angled down).
Samsung even places a 1 page insert in the packaging to tell you, you will see a brighter spot in the middle (when the TV is off) if you have a direct light source shining straight at the TV.
I realize the TV is on, in that picture, but it's the same principle. Also the camera (even if the flash where off) is not centered and not perpendicular to the TV.
Net: home pictures are good to show the setup, the TV stand, some weird artifact on a problem TV, etc. They are not good to discern technical details.
