Rivian Infortainment Issue: Google cast not filling up entire screen and no surround sound

Ever since I got my R1S, I've noticed that the battery range estimation hasn't been the best. Driving a Tesla for the last 3 years, it never had this kind of issue. During my last trip, the driver display shows 255mi remaining. My total trip (including 2 destinations) is 160mi so I believed I should be able to make it easily with a nice cushion. But the center display showed that I would arrive at first destination with 4mi remaining, and run out before the second destination! I knew this was false so I made the drive anyway, and arrived at second destination with 50mi remaining. If I understand correctly, the driver display range is simply the total rated range multiplied by SOC. That makes sense here, since my vehicle is rated for 370mi, 255mi is 68.9%. Coming from Tesla, I expect the number shown in the center display should account for factors like elevation, wind, traffic speed, etc. It's sad that my own mental estimation is better than Rivian's.

Streaming movies with Google Cast doesn't fill the entire screen, and there's no surround sound. I've tried Disney+, Plex, and Movies Anywhere. I haven't experimented with casting much yet, but I'm wondering if the aspect ratio and sound quality are determined by the source app, then the phone, and finally the available settings in the Rivian.

I can probably put up with the smaller screen, but the lack of surround sound is a bit disappointing. Someone suggested that it's likely because the app I'm using doesn't support Atmos sound or the movie wasn't recorded in Atmos. I might try this out to see if it works.

Note: I barely stream movies with my Rivian, probably why I haven't noticed this any sooner.
