Describe the bug

Hi. My old iPhone broke recently and I had to buy a new one. But today I tried to start developing some of the DNG negatives I'd taken with my new iPhone 16 Pro Max, and they load as a pixel question mark, and I get a notification saying "The image 'UTWY1533.DNG' is not supported." And I can't open them.

As far as I could tell (and I did check), I'm not using Apple ProRAW or anything. The photos were taken using ProCam by Tinkerworks. The DNG files just aren't supported for some reason.

Steps to reproduce
  1. Import the attached DNG into darktable.
  2. Notice that it can't be opened.
Example DNG

UTWY1533.DNG.zip

Where did you obtain darktable from?

darktable.org / GitHub release

darktable version

5.0.1

What OS are you using?

Windows 10

What is the version of your OS?

Windows 10 64-bit

Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip

My old phone was an iPhone 6s+ (edit: 11 Pro Max), and DNGs from that phone worked great in darktable.
