I haven't checked it myself, but I would expect song files, even if recorded on a Disklavier to show the full range of velocities played by the pianist. The velocity limitations of a Disklavier are not down to the fact that the sensors can't capture the full range of velocities, they are down to the fact that the solenoids have to overcome the inertia of the mechanical keys/action, as well as avoiding damage to the action from excessive force.
With modern Disklaviers, the introduction of servo control allows much more precise control of the keys which results in a more accurate playback at velocities near the upper and lower limits - the E3 can play quieter than anything else produced to date.
