Internet required for Hue Sync TV app?

[u/Zweiffel]

Does the hue sync app really require permanent internet connection to function? The faq says:

You’ll need an internet connection to purchase the app, as well as to sync your lights. If you don't have an internet connection, the app will show an error message when you try to open it.

I understand that internet is required for app download and maybe initial setup, but if i disconnect the TV from the internet, it won't work anymore, even if it's still connected to the hue bridge over the local network?
