When I pulled up Stargate SG1, I watched on Amazon Prime Video and Pluto. On Amazon Prime, I received the black bars. On PlutoTV, I did not receive the black bars. Tried in both 720p and 1080p Standard Mode.
On Prime Video, I did not see "All", but I did see 13+ (as in a rating for violence and language) in upper left.
On my TV remote (Mitsubishi), not my Roku remote, I pressed my Format button and put the aspect into Wide Expand mode to remove bars seen on Prime Video. Perhaps look for a similar button on your TV remote. (sometimes Picture, Aspect, or the like).
