I just did some more research and we probably won't do the work until there's more demand. We can actually easily support it on desktop (we upload the raw bytes but always default to serving a compressed version, which I can override for HDR) but for mobile there's no drop-in solution for Expo apps and thus would have to build 4 new things (iOS and Android uploader and display components). That said, I'd like to do this because I want PIECES to have a rich visual experience and was thinking of recruiting more photographers, but probably not now. Thanks for your interest though.
