Well, my concerns have been put to rest. Another thing that I realized about the suspect monitors at work is that they're shadow-mask type monitors, which display darker than those using trinitron technology. It didn't occur to me sooner because everyone quit making the stupid things five or six years ago. I got out of the habit of even having to think about them.
Of course, now LCD's are supplanting CRT's, and there's a whole wide range of quality available on them.
The color and exposure values on the jpegs I've posted seem to be pretty close to as good as it gets, from what I've gathered from this survey.
Again, I appreciate you all taking the time to help!
