Going of on tangent asking this but have any games ever shipped with colour charts for calibration with different monitors?
No proper calibration, but the closest I've seen is in the Myst series. According to my fuzzy memory, either Riven or Exile (or both) had a setup screen with shades of gray, it instructed you to adjust the brightness / contrast of your monitor until the shades looked a certain way. My search-fu is failing me on this, so maybe it's a fabricated memory.
