Most digital still cameras use the sRGB gamut (same as HDTV), and computer monitor primaries are similar, so showing what the sets actually look like to the eye will be a problem (although you should be able to see a difference of some kind in photos of the two screens).
Years back, a SMPTE monitor committee had two identical tubes made up (by Sylvania, IIRC) except for the green phosphor, one sulfide green and one NTSC green.. They were mounted in identical monitors and set up in the engineering lab studio at NBC in New York. They had some brightly colored objects in front of the camera including something "Kelly green". With this setup you could clearly see the difference, not only in the greens, but in the cyan saturation and the relative brightness of cyans and reds. They eventually demonstrated that you could get reasonable/acceptable (though not perfect) rendition of colors within the sulfide gamut by changing the matrix in the monitor. As a result, future monitors (Like the Tektronix Trinitron-based series) had a switch to turn the matrix adjustment on and off. You would set up the hue and chroma on color bars with the switch off, then turn it on to get reasonable flesh tones.
