Lightroom iOS HDR images cannot be edited as raw

DNG HDR images taken using Lightroom iOS cannot be correctly imported as raw to Photo AI. The colours are wrong, entire image is washed out and purple tinted.

This was a problem with previous versions, but the notes for 1.2.4 said that HDR DNG images are supported.

Steps to reproduce issue:

  1. Step 1
    Take HDR photo using Lightroom for iOS (iPhone)
  2. Step 2
    Open Lightroom on Windows and sync cloud images.
  3. Step 3
    Open locally synced image in Photo AI using Plugin Extras, Process with Photo AI

Topaz Photo AI [v1.2.4] on [Windows/Mac]

That is Lightroom HDR images generated in the Lightroom desktop application.
