Yes, but not that much. Some tests I did a year or two ago indicated that 
the difference was only major for very edgy waveforms and even then the 
only real difference was between the original edgy waveform and any phase 
randomized one (phase randomized with different phases all sounded pretty 
much the same).

Controlling the general inharmonicity and amplitude envelope of individual 
harmonics is much more useful.
