Long runs of no changes is generally undesirable because it makes it harder to know where the reader is. So you’d want some type of coding to make sure you see changes occasionally regardless of where you are. For CDs, it seems like each byte is converted into 14 bits, where the longest run of zeroes is 10.
I know, among other things there is a time code inserted very frequently between audio data, without which seeking would not be possible at all. However, the audio uses over 90 % of the data so it’s largely responsible for the overall appearance of the track.

It doesn’t seem like there’s a pseudorandom coding applied, so repeated patterns should show up visibly. I’ve never really examined it myself though.
Welp, I remembered this post and it’s most likely valid CD-audio, just with awful noise.
Cool! Good to know this software is out there.
