Here's some tips on how to get a better picture (not calibrated, but better than the vivid mode)
Change picture mode to standard. Lower sharpness to around 30.
Enter advanced control. Change colour temperature to warm and turn all the XD-engines off (contrast, colour).
Turn the noise reduction off. Gamma to medium and black level to high.
Now go back and adjust the backlight, contrast, brightness and colour to a setting that look good in your environment. I usually turn down backlight and contrast to about 60, but try and see what's works for you.
