2025 Lightroom and Photoshop have a vastly better HDR workflow for working with RAW and exporting to AVIF or JPEG with embedded HDR luminance map that shows up correctly on iOS or in Chrome on MacOS with the display set to HDR. I don’t know about Android or windows.

I have re-exported files that I took in 2007 with the Nikon D7 that I kept the raw files for. They are vastly improved with modern processing (and noise reduction) vs what I exported from the same negative back then. The bit depth was always high enough.
