Andrew,
That's easy.
Just assign the different RGB spaces you want to compare to my RGBXPLORER
image (www.hutchcolor.com/Images_and_targets.html) and then convert to
whatever output device you like with whatever intent you like.
Look at the channels and you'll see that some colors (e.g. bright reds)
which should have printed 100% Magenta will be clipped at a lower number,
e.g. 95%, when the RGB space was INSIDE the gamut of the output device.
