Eight bits per color is certainly as good or better than typical video
systems.  Production quality video cameras (including HDTV types) typically
have a dynamic range of 40 to 50 dB in each color channel.  High-quality
CRT and projection displays are little better.  Eight bit channels have
a signal-to-noise ratio of 49 to 50 dB.  Only very specialized systems
would need more than eight bits per color channel.

p.s.  I suspect that "true color" refers to direct storage of RGB values
      in video RAM as opposed to the use of color palette lookup tables.
