In which case the speculation I have occasionally seen on the web that
some early CDs lacked dither is probably inaccurate.

Not necessarily. The fact that some people knew what dither was, and why it
might be required, does not guarantee that everyone making every CD falls
within this class of people. Although they may well have been saved by the
noise levels on the original analogue tapes where they were used as the
source. :-)
