That's kind of like saying storing files in a zip is worse than storing them uncompressed.
Or like the "what color are your bits": https://ansuz.sooke.bc.ca/entry/23
Kind of, except anything that moves can not move, so the simple act of decompression can introduce errors that simply wont occur in the raw PCM-wrapped WAV file since nothing has been compressed at all (hence no extra moving part).
I really liked that linked article btw.
