RAW profiles (like Adobe RAW and Camera Matching profiles), are not available for photos that I've taken on my new phone (iPhone 11 Pro Max, iOS 13.1). They *are* still available for photos taken on my previous phone (iPhone X, iOS 12.4.1), including photos taken since I got the new phone.
This seems to happen for any RAW files, whether taken with the camera in the Lightroom iOS app, or with another third-party app, like Halide. It occurs when I view the files in Lightroom on either phone.
On the left is what I see for RAW photos taken on the old phone. On the right is what I see for RAW photos taken on my new phone. I have tried removing and re-installing the Lightroom iOS app, and of course restarting my phone.
I verified that this is also true on Lightroom for desktop, which I re-installed just now.
This seems like an issue with reading the file metadata—not recognizing that a RAW photo taken on the new phone is actually RAW (and thus eligible for the RAW profiles). I have attached two example DNG files, both taken with the Lightroom iOS app camera. (I used the HDR mode, but non-HDR photos behave the same.)
Here are two example files (which I was not able to attach here due to an error: "The attachment's content type (image/x-adobe-dng) does not match its file extension and has been removed.")
RAW profiles available—RAW photo taken with iPhone X, iOS 12.4.1, Lightroom HDR camera:
Since the iPhone 11 Pro has been recently released the support for the RAW images clicked using the phone has not been included in the application and would be included in a future update post which you should be able to select the relevant profiles for the images you click with the new iPhone similar to the iPhone X.
We currently do not have an estimated time on when the new iPhones would included in the applications for full support. You can refer to the list in the link below as it is updated after every software update.
