Plex Media Server considers the TV to be “Generic.” Therefore, it has limited playback capabilities.
It supports only H.264 8-bit video at 1080p or lower resolutions. Any other video, including HEVC, will transcode. Also, only AAC 2.0 audio is supported. Any audio with more channels or using a different codec will transcode.
I’m not sure why the HEVC video will not successfully transcode and play. The server is clearly powerful enough (AMD EPYC 7713P CPU).
However, it is expected that HEVC video will transcode.
FYI, the log files show the TV to be a Foxxum brand, not a Hisense R6 Roku TV or a Hisense running VIDAA OS.
Foxxum is partnered with Hisense. However, Plex thinks the TV is from Foxxum, not Hisense.
Additional detail:
The log files indicate the TV is a Foxxum.

As you can see from the log entry, Plex considers this a “Generic” TV.
Also, look at the Plex Dashboard & Tautulli screenshots you provided. They show the TV as “Plex for Smart TVs.”
Now look at the Devices with Limited Playback Capabilities section of Which Smart TV models are supported?
Plex for Smart TVs: If the value is simply “Plex for Smart TVs” (and not a specific brand), then that means the app does have limited playback capabilities.
