Can you share the main jellyfin log? It contains the reason the video was transcoded. The codec is H264, level 41. Pretty pedestrian. So I suspect the Fire TV is transcoding due to "ContainerBitrateExceeded". This is a bug in the Android TV app where the "auto" max bit rate settings is too low. Try manually setting the max bit rate setting in Android TV to 120Mbps.
