Lightroom seems determined not to support HEIC export, even though iOS has trouble with all of Lightroom’s other HDR formats. From my testing: - JPEG with HDR gain map is not supported - AVIF and JXL HDR files look fine on initial export, but do not survive being sent anywhere from the Photo Library. So far I haven’t found a way to export an HDR file from Lightroom and then share it with anyone, iOS or Android.
