I would like to ask you for your comments on what I have suggested.

I already linked to the description of the options:

--dhdr10-info <filename>

Inserts tone mapping information as an SEI message. It takes as input, the path to the JSON file containing the Creative Intent Metadata to be encoded as Dynamic Tone Mapping into the bitstream.

Click here for the syntax of the metadata file. A sample JSON file is available in the downloads page

source: https://x265.readthedocs.io/en/default/c...hdr10-info
and

--dhdr10-opt, --no-dhdr10-opt

Limits the frames for which tone mapping information is inserted as SEI message. Inserts SEI only for IDR frames and for frames where tone mapping information has changed.

source: https://x265.readthedocs.io/en/default/c...dhdr10-opt

So with the first option you add your meta data and with the second once you tell x265 to minimize the overhead through that meta data.
Not sure how I could help more.
