You can see sidebands from 1kHz pitch update rate if you deeply modulate the oscillator's pitch with a fast enough LFO and look at the spectrum. I think you'd be hard pushed to hear the sidebands for low-pitched notes using typically rich oscillator waveforms where the dense harmonics of the waveform would perceptually mask any low-level inharmonic sidebands.
