I think Gugliel's idea of modifying individual notes is theoretically the answer, but of course we would all go mad if we had to do that. I find it often too laborious to even instert the right crescendo articulations etc.
I have always noticed that on my recordings the VSL samples sound thinner compared to the live sections - for example my average (live) violins sections are only 5 + 5 and sound still much bigger than VSL's 14+14 or for example I recently recorded a French Horn section with just 3 horns and they sounded huge - compare that with playing chords played the with the VSL Horns Ensemble (4+4+4= theoretically 12 horns! but sound quite small).
Apart from the 3.5k dip and 12k "air" boost, that Dietz mentions too, the live recordings don't need any postproduction.
I think ulitmately we could get closer to expressive lines by having more realtime control over vibrato and dynamics (real, not crossfaded) but I wouldn't know how this could be done with samples.
