Netflix is kind of an exception to this because you're not buying the exact same service in each country, Show/Movie availability differs per country, but also some regional audio/subtitles availability differs per country (there's a language setting in your account settings but it doesn't have all the audio/subtitle languages netflix supports, even though the number of options has grown since last time I checked it...)

And thanks to another EU law if you subscribe to Netflix in one EU country, you get that country's Netflix Library everywhere in EU. So we can talk about "Swedish Netflix" and "Bulgarian Netflix" as two different services..
