If you have a low level (below 1/2 LSB) analog signal that is recorded with a PCM ADC then that signal will be lost (without dither) or it will be encoded as pulse density (with dither). In other words, properly implemented PCM uses pulse density as one of its encoding mechanisms, and as the signal level gets lower this mechanism becomes more and more important. In a 1 bit system all signals are low level, so pulse density is paramount. This is consistent with my observation that DSD is a special case of the more general PCM model.
