Look, service mode is just a white line across the screen, right? If so then I can make that happen with a computer graphic.

No, setup is a very nearly black line that is visible because it is all the lines in the raster falling on top of each other. It also requires that the video circuit is disabled except for a fixed bias applied. The aim is to have the video output stage biased to a known voltage that should represent black and then adjust the CRT G2 voltages so that it actually is nearly black. Then when the service switch is set to normal, the blacks in the picture are neutral and all the gray levels are the same neutral.
