Correct.
Transfers from non-UK dom to UK dom are made up of nil rate band of £325,000 plus £55,000 exempt (ie strictly nil rate band not £380,000), but know what you mean.
Because of the DTA is may be theoretically possible for husband to die Italian domiciled and at that time for wife to be UK domiciled or vice versa; although in practice i would have thought unlikely.
Domicile requires a factual determination.
If you are concerned it may be worth talking professional advice.
