Both cameras have a Quiet mode that is selectable on the release mode dial on the top of the camera. I assume that is what you are talking about.
The D4 also has a Silent mode that is only available in LiveView. See page 60 of the English manual for details and limitations. This mode is not available in the D800.
Quiet mode reduces noise in viewfinder mode by delaying the mirror return until you lift your finger from the shutter release button. It is not silent though.
Quiet mode in LiveView is quieter than Quiet mode in Viewfinder mode, but still not silent. In LiveView mode I cannot detect and difference between Single release and Quite release mode, probably because the mirror is not part of the operation.
The D4 LiveView Silent mode is silent. Apparently it does electronic shuttering instead of mechanical shuttering.
