It seems Samsung has a 80 Mbps (80000 kbps) limit for H.265 video. See this post for details. Another post mention a 60 Mbps limit for H.264 video.
The video stream for Lucy is above the 80 Mbps limit. See log files below.
Plex normally transcodes the video to a lower rate. However, you disabled video transcoding, so Plex cannot play the movie.
You would not want to transcode Lucy anyway. Plex Media Server transcodes all video to H.264 SDR, but does not map HDR to SDR, so transcoded HDR usually appears with washed out colors.
I did not notice a fix/workaround posted on the forum (I searched for “Samsung 80000”).
For movies where the total bitrate is over 80 Mbps (video + audio + subtitles), but the video is under 80 Mbps, you might be able to remove unnecessary audio and subtitle tracks to drop the overall rate below 80 Mbps.
The only solution of which I’m aware would be to purchase a streaming device such as an Nvidia Shield Pro, Roku, AppleTV 4K, etc.
Hopefully someone with a Tizen based Samsung can weigh in with additional information.
