Real dynamic range of CD in terms of information rather than max SNR is 96dB. You can lower the noise floor but I don't think anyone thinks there's real information to be had below -96.
Incidentally, Dolby SR on a fast analogue tape could give you over 100dB based on SNR according to the Wikipedia article on audio dynamic range though 95dB would be a more common claim, and the information content would be real to well below the noise. And no brickwall is needed.
Again, it all depends on how the ear works. Not on high level THD IMO. We don't listen to sine waves.
So does DSD have only 1-bit informational content? And aren't those Dolby numbers dependent on frequency? Re sine waves: if you make a trigonometric reconstruction based on the DFT, you will get something that sounds a gosh-awful like the music you are reconstructing...
