No, those people don't use samples - we are talking full-size grand pianos here.
Those Disklaviers record and play back performances on actual concert instruments.
Think of it as a digital version of a Welte-Mignon player piano (the company has it's origins
here in Freiburg/Germany). The local museum does regular concerts with roles recorded by
famous soloist/composers from the first half of the last century.
IIRC the velocity resolution on those roles is higher than the 7 bits used by midi.

IIRC the Roli keyboards have better resolution and those are used quite often for
contemporary music performance.
Some Casio E-Pianos seem to have high-resolution velocity values (14 bit), see

Not what our piano teachers say ;-)
