The monitor would have full DC restoration, while the consumer set would not. The high voltage would be regulated more closely than on a consumer set, meaning the raster geometry would not change with beam current. [Later pro monitors had a separate HV supply and horizontal sweep - I do not know what was in this one.] The monitor MAY have had the white point set to Illuminant C if the owner was careful and had the proper equipment, but the consumer set definitely would be set much bluer. The monitor may have had color matrix adjustments rather than fixed resistors - don't know without seeing a schematic. Also do not know if the monitor had any more elaborate convergence circuits.
The picture tube on this monitor has the greenish color typical of sulfide phosphors, which means it would not have NTSC primaries, but would have the same primaries as consumer sets. Much later, SMPTE would adopt the "C" (for Conrac) phosphors as a standard, which were not NTSC either.
