Yes it would. But ITV Channel Television is more a case for giving each channel their own branding, rather than the dual branding, with the clear main brand being Channel

That doesn't make any sense. The Isle of Man isn't part of the UK either, but I've never heard of street riots there about them being branded ITV or ITV1.

I wasn't aware that ITV in the Channel Islands still had other than the generic ITV/ITV1 idents.

ITV1 is a national channel. They really abandoned regional identities within all their broadcast areas (including those outside UK territory) many years ago. They just retained the 'lip service' of regional news under the terms of their PSB licence.
