I suggest Affinity Photo (iPad) to support displaying and exporting High Dynamic Range HEIF (HDR PQ 10-bit) from RAW/DNG/ProRAW file.
It could really be a killer feature in photo editing across any OS platforms. It is especially benefitial to users who are using some recent iPads supporting HDR10 (e.g. iPad Pro 2021 with XDR display). For compatibility in web publishing, HDR-PQ-like JPEG could also be supported, just like what Canon is doing. (Ref: https://snapshot.canon-asia.com/article ... ts-of-jpeg)
