Yeah this has been fun to explain to people haha. We also get surveys that we can't interact with. I haven't found any way to turn this off.
ADBTuner doesn't support HLS. MPEG-TS should be preferred on a local network anyway as it has lower latency.
As for the settings, It's helpful on all of these devices to disable the stream formats you aren't using. For example, disable HLS, RTMP, RTSP, Multicast, and and any alternate resolution versions. This will lower CPU usage and improve performance.
6,000 mbps h264 @ 60fps seems reasonable.
