Just an update -- seems that Jellyfin uses an extremely high bitrate (139808000) when streaming live TV over DLNA with QSV per this command: -low_power 1 -preset veryfast -b:v 139808000 -maxrate 139808000 -bufsize 279616000
The b:v flag is not used when VAAPI or None is selected for transcoding. The network adapter on the server shows that it is taking an 8Mbps stream and sending 140Mbps to the client and creating a 140Mbps .ts file in the transcode directory. Definitely looks like a bug with Jellyfin since I'm using the latest server version and latest Intel GPU drivers.
