I'm not an expert here but I would guess probably not.  the
difference is in the noise, which a lossless codec has to
preserve.  if you do two recordings of the same noisy source,
the one with the higher sample rate will have more information
in the form of noise.

a higher bit depth should theoretically not make as much of a
difference assuming the DACs inject the same amount of noise,
but I don't know if that holds in reality with higher bit
depths.
