Is it possible to direct stream HEVC to chromecast ultra?

Hi!
For starters, has used serviio for a couple of years now (running 1.10.1) and it has worked flawlessly direct streaming my movie collection to chromecast 2nd gen. I love it
Video files:
mp4 container
x264 4.1@high
first audio aac stereo
second audio ac3 5.1
no subtitles

I'm thinking of reencoding all bluray movies to same specs, replacing video stream with x265 8 bit main and direct stream to my chromecast ultra. Has done some tests and when casting AVC movies to chromecast ultra, application-profile "chromecast" is used and everything works. When casting HEVC nothing happens and I cannot find any information in logfile.
If I add below to "chromecast" section in application-profiles.xml....

<Video targetContainer="applehttp" >
<Matches container="mp4" vCodec="h265" aCodec="aac" />
</Video>

...this shows up in logfile...

Is there some way to make this work?

It appears that the Chromecast Ultra supports 4K/HDR/DV, so it must support H.265. There should be no need to transcode the video. If you need to transcode the audio, that would be different, but it's possible to transcode only the audio and leave the video alone.

Your transcoding line seems incomplete. The only thing it's accomplishing is changing the container from MP4 to HLS. From what I can find online, your Ultra supports the MP4 container, H.265 video and AAC audio. No transcoding should be required at all.

I agree, this is weird, direct play of same file works fine through plex.

If I don't alter application-profiles.xml nothing happens at all, no lines in logfile nothing....
I can't get a grip of what the problem is.

Casting the same movie, only difference between files is video stream x264...
