The whole point of the sampling theorem is that the samples define ALL of a complete and continuous analogue waveform of any complexity, as long as the original waveform was band limited when was sampled! You imply the smoothing is done using a best guess algorithm but there is no guesswork, only one analogue re-creation is a valid solution. E.g. a 20kHz sine wave will have only about two samples per cycle yet the re-created wave will look like a perfect sine, not a saw tooth. To repeat, as long as it was band limited to begin with, this is the magic of the sampling theorem.
