If the capture is destroyed by "the bits after that" then it is destroyed.
The capture is generally "destroyed" by:
a) the lack of sufficient "bits"
b) the use of inadequate methods to reconstruct it from "the bits"
Once you get more than enough bits, any supplemental "bits after that" won't make a noticeable difference. When increasing the number of bits, different methods of digital encoding/reconstruction will just converge to similar end results.
What I find interesting is that people use the term "lossless" or "uncompressed" audio when referring to raw LPCM / DSD digital audio. It sure as hell is "lossy" as some information from the original analog signal has been discarded / altered. It's a just a different kind of "loss" than with an MP3 file.
