I think it is the clamping by the saddle and some clamping by the bridge 
(which moves so not as much clamping as at the saddle) and the stiffness 
of the string which produces a small innharmonicity in the strings partials.

I agree!

There is some truth in it, but this is not the main reason, I think.
I would say together with vibrato or sound fluctuations the resonating 
body makes the sound more lively since the rather fixed body resonances 
interact with the moving string frequencies and change the spectrum 
constantly. So you need to look at what the player does with the 
instrument too.
