As you can see, by zooming in the area of clipping, the recording clearly exhibit 0dBFS+ levels (as well as possibly clipped digital samples):

Here is how the Track 1 of the CD-R looks like:
Track 1 of the CD-R (recorded using soundcard at 96/24)
As you would expect, there are no frequency components above 22.05kHz. I'm not quite sure what the noise around 15.6kHz is, quite possibly this is an artefact from the equipment used in the studio (carrier frequency of a wireless microphone, perhaps?).
Here is a frequency analysis of a representative point in the recording showing the presence of the 15.6kHz signal:

The noise is also present in the CD layer:

As you can see, the artefact is also present in the remastered version.
