Dunno about YULS, I only tested ffmpeg bundled codecs thats why lagarith wasnt inlcuded, as Zarxrax mentioned, it should be somewere between UT Video and FFV1.

I tried AV1 lossless, but its so slow that I didnt even bother letting it finish. Someone that has a faster CPU/has more interested in tuning it for some speed maybe can give an comparison on how good the compression is in lossless mode. But I'm pretty sure that it will keep being to slow offer any real life value when in comes to lossless compression for quite some time.
Why is x265 the only option for HDR? As long as the codec supports the pixel format it should be fine for HDR content, no? Are we discussing real world applications here? Is there a specific workflow need that you have for these lossless questions or are we just talking compression in general?
