Basically what the title says... notice the 'plus' in HDR10+, as I would like a flow that retains dynamic (frame/scene-level) luma info

I'd like to convert a file recorded from an iPhone 12+ to a royalty-free version (for upload to Wikimedia, Flickr, etc). So the transfer involves:

Source (iPhone proprietary-encumbered) Destination (royalty-free)
4k 60fps (UHD, not DCI) 4k 60fps
BT.2020 in HLG (WCG) BT.2020 in HLG (WCG)
Frame-level dynamic HDR metadata in Dolby Vision profile 8.4 Frame-level dynamic HDR metadata in HDR10+
HEVC VP9 (open to AV1 as well but that's likely more nascent)
Bitrate is 31 Mb/s Fine with higher bitrate to maintain same SSIM/PSNR
Audio is in AAC Audio to Vorbis/OGG
