I (UK) also got the renewal email last night. I'm also very sceptical that the new and improved video player will be anything of the sort. There's also a list of eligible countries here:
https://nhl-support.zendesk.com/hc/en-us/articles/5584014279324-NHL-TV
It lists Scotland, England and "South Wales" (
apparently a thing) alongside United Kingdom, but not Northern Ireland or Wales. It also lists "Zaire", which was renamed as the Democratic Republic the Congo 25 years ago.
Based on past experience, if you were able to make your viewing device appear as if it was based in one of those countries, you would get the full NHL TV package. At least auto-renewal is off this season, we'll be able to tell if this is still the case.
