I have a couple different calibration discs and each has a bunch of different color bar patterns. If I display one of these patterns, is it the same to the TV and testing as if it came from a generator?

The signal from a DVD will be even more accurate than from most service-grade test generators. Cheaper generators will have simple sync signals without all the FCC details like vertical equalizing pulses.

As long as the pattern has all three colors, you should SEE all three colors ON THE SCREEN, but if the pattern is not the one specified in the service manual, the waveforms will be different from the service manual.
