The audio standard in the movie industry, from production to finished
mix, is 24 Bit, 48kHz, BWF. It won't get any better that that, even for
new releases (born digital). For everything pre BluRay, the audio has
been most likely re-purposed from the NTSC DVD it was originally
released on (16/48 which, was 24 bit truncated to 16 bit). I'm even
aware of situations where the original files for the standard definition
DVD were unable to be restored from archival copies and the producing
company resorted to ripping, and then converting, the AC3 file from a
commercial release for re-purposing to BluRay.
Sorry if I burst your bubble.
