Yes. It's not about subtle differences. So, are the differences spectrally subtle or not? Measure them. Surely somebody must have done so already, no?

Keep in mind that the human auditory system is nonlinear with respect to the relationship between what we report to hear and what the input is. For example, if two long pure sine waves are presented to the ear we report to hear overtones and sums and differences of the two frequencies (not to be confused with "beats"). 

This complicates things a bit but a good place to start is with the input. Do the measurement.
