I don't think you can add DolbyVision HDR (or HDR10+) data to av1 streams, since I suspect that, like with HEVC they would need to be embedded into the video stream.
In HEVC this is done through:
https://x265.readthedocs.io/en/master/cl...on-profile
and
https://x265.readthedocs.io/en/master/cl...on-profile
but I am not aware that there is a way to do this with any av1 encoder or that this would even be supported by any decoder.
My guess is, that you only set the normal HDR10 metadata, not the dynamic metadata and thus only use the HDR10 compatibility.

If you use mkv as container, you might also have to set the HDR10 metadata in the mkv container. Can't remember who, but a while ago some user had this issue that HDR wasn't working with his player and we figured it out that the player for mkv only read the metadata from the container.
