Sure, CRTs have better contrast than LCDs in general, but monochrome CRTs have incredible contrast. I guess it's because they don't have separate red / green / blue subpixels (2/3rds of which would be off for green on a color CRT). Also, the particular shade of green phosphor they use is really intense, I guess they just use the wavelength the eye is most sensitive too, because they don't care about how it mixes with other colors.
