Higher bit rates help with dynamics processing. It helps only in the sense that having no signal energy above Fs/4 or Fs/8 allows simple algorithms to produce acceptable results. For example any effect that requires fractional sample or continuously variable delays can use simple linear interpolation when working at 96 or 192 kHz. Doing this at 48 kHz would produce audible artefacts, and to avoid these you need higher order interpolation, which amounts to the same thing as resampling. Fast limiting benefits from higher sample rates as well, but it can be done inside the limiter - there's no need to use 96 kHz everywhere.
