Do you mean "euroroaming zone" or "zone for outgoing calls from the home country"?
You're basically right about second option, I think. As you said, the difference in pricing (if any) between UK and the crown dependencies with the +44 numbering may occur for VoIP providers. In Poland, so far I've only one VoIP provider which charges moreless twice as much calls to +4476, +4479 and 3UK than to other +44 mobiles. No mobile or landline provider distinguishes those territories.
However, with roaming the things are different. So far, 3 out of 4 operators here declared their euroroaming tariffs. Plus and Play don't mention about Channel Is/IoM so they probably consider them as parts of UK. However, Era in its roaming tariffs declared those territories explicitly as non-EU (both as origin and destination of calls).
