I think you are missing the point in 2 ways Simon. The intro of colour management is aimed at showing any profile as correctly as it can be shown on a sRGB monitor as the vast bulk of monitors by an absolutely enormous amount are sRGB and often poorly calibrated which is an entirely different problem.
In some ways this doesn't make much sense as certain aRGB colours just can't be shown on a sRGB monitor. The same is true the other way round however as the gradation of sRGB is smaller not so noticeable.
The other is a miss understanding about aRGB that I had some time ago due to the web. It has the same number of colours as sRGB but they are wider spaced. I gained the impression that it was a 3x10bit colour space. Try this page
