Weird, why just on opera? It uses the same engine (chromium) as many other browsers.

		I'm guessing because of a higher widevine certification level or a server-side policy? You can also spoof Opera's user agent and get 1080p on FF so guessing it's a server-side thing; since Linux has L3 widevine certification because no kernel level TEE

		I have no issues on Firefox FWIW. I haven't needed to spoof the user agent, though this is something I needed to back in the day when they literally blocked FF's user agent.
