As it's well known that the ear can detect signals from actually below
the noise level in some circumstances, the benefit of dither is pretty
obvious in a digital audio signal and are certainly nothing to do with
the filtering. As you know the filtering is required anyway due to,
well, "Nyquist stuff".

Funnily enough, Pioneer's highly respected plasma TVs used masses of
dither to hide solarisation and colour banding in TV images too, as do
many others now. The Panasonic's do it too, but not so aggressively.
Plus of course cheap LCD displays dither when it suits them too.
