I think the distinction on speed of refund is not so much around exUK or exEU, but whether it needs a manual calculation or the value is clear and can just be automatically processed - a bit like whether you get an offline FTV or an online evoucher if you go down that route. Things like upgrades and changes are more likely to require a manual calculation.

FWIW I have had the same email for a refund on a UK domestic return, originally a LHR-INV which had several invol changes and eventually the last invol change was to turn it in to a LHR-ABZ rtn, This has been pending since mid December.
