No, you can't reduce the video bitrate on a channel. You can set your Roku to a lower screen resolution, which in theory should reduce your bitrate somewhat. But the most important thing you can to is to complain to Paramount. They have sole responsibility and control of their app/channel. There's nothing Roku can do to resolve an issue with a 3rd party app.
I talked to Paramount Plus and the techs thought I was insane. Said it was coincidence that the TV overheated on their str service. They blame it on the TV, even though, for me, it only happens on their "channel."
