Disney+subscription through Disney directly does not work for tvs with roku at all, so the real answer is apparently no, you must have two separate subscriptions for each TV.

Nope, not the case. We use the Disney+ channel on multiple Roku and Android players, all using the same Disney account. And our Disney subscription is directly with Disney, not through Roku or any other 3rd party.
Be sure you're using the actual Disney app on your Roku and not trying to view it inside The Roku Channel app
