Graeme;
As you may have seen, many multichannel profiles will contain good B2A tables and absolutely minimal A2B tables. That also makes the reverse process difficult, or highly inaccurate. (and happened in the majority of example multichannel profiles we found). We are trying to improve the technology to preview more than 4 channels in realtime, but with so many bad profiles to test against....

It's not the monitor colorspace that is a mystery, it's the colorspace
the multichannel file is in that's a mystery. If a multichannel
profile only contains a B2A table (naughty! - not compliant with
ICC specs!), then it's possible to convert into that space, but
not out again, so it's not possible to display it correctly
on the monitor.
