That is exactly what I think the "differences" really are. If you re-bias the tube to a different operating point the harmoinic content of the output signal will be different. The 6SN7 has a very large linear range compared to say a 12AT7 so it would have to be altered quite a bit but that could make for a very different response.

All of the tubes mentioned control current in a vacuum through wire leads. I'm not sure what about that would result in such a drastically different sound, especially something like "more forward". There are differences due to manufacturing but again if you bias near the midpoint these differences are minimal.

I belive you will find these differences to be orders of magnatude less than say the sound of different speakers.
