Might be. Not for mortals though.

I guess the best they do is 12 pits per channel. And that high contrast 
is usually not within a single frame, but between successive frames. 
Essentially it just tells you how much they automatically dim the 
backlight in dark scenes.

There are displays that can dim the backlight locally, giving them a 
comparatively high contrast between parts of a single scene - but even 
there it is used solely to get the "black" level down in dark parts of 
the scene.
