Are Languages & Countries of Origin only visible on the main title page?

...I mean, unless Title Reference View counts.

Good point. If the New Version persists as is, I may try to get used to Reference (if it stays). But that's actually worse for some titles, because more cast/crew is on the main page, with language & country after.

Given my IMDb site preferences, while I'm logged in, IMDb's web servers redirect every request for an IMDb title main page to the URL of the page's corresponding reference view. I've mostly kept this setting (rather the Title Combined View preference) unchanged since for two decades ago or so. I use a monkey script to emulate the comprehensiveness (and terseness) of the discontinued Name Reference View.

That's correct - at this time the Countries of Origin and Languages information are only found on the title page (and the Title Reference view).
