Are you asking about color detail or range of colors (gamut)?
The 15GP22 and 21AXP22 had NTSC green, giving more capability for saturated greens and cyans. Later tubes went to a yellower sulfide green that improved brightness, but cut the saturation on the cyan side.

Color detail is what all the discussion of bandwidth is about.
