This example has already been debunked a long time ago. These were screen captures somebody took from a Nikon video about those models. Obviously, nobody would buy a D800 or any camera for that matter if it delivered like that sample.
There have been a number of good comparisons posted over the last couple weeks on various sites, including full resolution jpegs as well as NEF files for both models that show the difference (or lack thereof) much better.
