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

A friend needed to support his son who would be running a 'very cold' marathon on Sunday while rucking a 30 pound pack. The outside temps will be around 15F-20F the whole time. The location of the race is nowhere close to any L2 chargers, but he's not worried about driving distance to or from the race - it is 50 miles away from his house. He says he will be sitting in his ruck with his laptop and watching his live track+Garmin inReach data for the duration of the race (about 4 hours). He thought about taking his Honda EB2800i gasoline powered generator, if he can use the level 1 EVSE attached to the generator and keep the truck running with full heat + power - without really consuming much of the truck's main battery? He feels it's super dorky to have a gas generator running while attached to a Rivian in the woods, just so he can stay warm, but don't know if it would work ok this way and 'preserve' the main battery so he doesn't need to worry about driving range when we wants to head home. He talked to me about it and I told him the simple answer is NO. I tested this theory the other night when I was plugged into a 5.9kW charger. To maintain the interior amenities (interior and exterior lights, radio, heater, seat heaters), it took almost all of the charge. I charged for 15 minutes, it delivered 1.6kW, and the truck consumed 1.4kW, delivering only 0.2kW to the truck battery. Told him he would be using a laptop at another 200ish watts. The little trickle charger charges at 1.4kW on a good day, 1.2kW is normal for me. You can slow the bleed, but you cant stop it. My advise to him was for him to charge it up to 100% at home, and roll the dice is what I would do.

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.
