Oh my - I just examined in detail the default settings that OldPete posted above, and see that the XBR has (2) MAX default image settings for Vivid.
For those who love viewing with the Vivid mode, you should reduce the settings, and NEVER watch any mode that has MAX for Backlight and Picture (as Vivid mode does).
ALL your other settings (especially color etc) are now oversaturated (with some bleeding or pressed colors), your light output is completely unnatural, and in dark scenes (especially with roomlights turned off) the black level is non-existent and will reveal itself as GRAY.
You can compensate with a lower brightness, but still with MAX present for Backlight and Picture [contrast], your images are not normal but instead are illuminated and oversaturated.
Either lose the Vivid setting, or lower it's MAX settings for sure.
