This is BT.709 Gamut (pretty close to 601 and NTSC) with the fullrange exposed. The primary reason 16-235 was chosen for digitization was because of the expectation that wider gamuts would shortly come into use; turns out they were about 20 years too early.

You can process it all you want in Avisynth, as long as it can read the container format, just don't convert it into 8-bit RGB or you'll lose all the extended range. You need a tool to convert it to 16-bit or higher RGB to be useful.

Despite what wiki sez, most cheap LCDs have a gamut limited to sRGB or at most approaching NTSC, though, so don't expect it to automatically translate to vibrance unless you have something like a new Bravia or another LED backlit set.
