HDR previews for RAWs?

With HDR screens getting more and more common (OLED mobile phones & TVs, XDR display iPads & Macbook Pros), is it possible for mylio to add HDR rendering support to previews and masters that have HDR support? I think almost all RAWs have that support implictly and a lot of newer smartphone photos do have it too now.

I know a lot of previews would have to be regenerated, or we might need HDR & non-HDR preview copies for things to look right, but I think we would be ok with that as a one time operation. Devices that are not vaults can only keep one type of preview depending on their screen type.
