Lightroom Fails to Apply Built-In Lens Correction for iPhone 13 Pro

[JCW2]

For Apple iPhone 13 Pro there is an in-camera lens correction for the "Ultra-Wide" lens (and probably for the front, selfie, lens as well) that is applied automatically to photos made in JPEG format.  For the ProRaw format, this lens correction (and probably that for the front camera) SHOULD be included in the corresponging DNG file.  Lightroom Classic (now using 12.0.1), however, does NOT apply this correction on import, even though I have used Copy and requested in Preferences/Presets that "Camera Settings" be applied for this specific camera.

Since Adobe has (reasonably) not provided (presumed redundant) lens corrections for this lens, there seems no way to correct it in Lightroom.  Am I doing something wrong, or is there a bug in Lightroom? -- JCW2

Doesn't anyone here have an iPhone 13 Pro?  If so, can you please try taking an Ultra-Wide photo in ProRaw format and importing it into Lightroom?

Does it get the lens corrections done automatically in Lightroom?  (You may or may not have to set "Camera Settings" in Edit/Preferences/Presets/Global to make this happen.)  If so, the Develop/Lens Corrections panel should show "Built-in lens profile applied" at the bottom.  If not, there should be an obvious difference in perspective and depth compared to a JPEG photo of the same scene (which has the lens corrections applied in camera). -- JCW2

According to: https://helpx.adobe.com/camera-raw/kb/supported-lenses.html 

The UW lens does not yet have an Adobe-supplied profile for the Ultra Wide: ƒ/1.8

I understand that, Rikk, but my point is that Lightroom is not applying the built-in lens corrections from the camera for this lens on import.  I have two pieces of evidence for this statement:
1) The Develop/Lens Corrections box does not show "Built-in lens corrections applied" for the ProRaw (DNG) image.

2) Comparison between the ProRaw image and an identical shot made with the same lens in JPEG format and also imported shows an obvious difference in depth and perspective.  (Of course the camera applies its own lens corrections to the JPEG image.)

Still nobody trying to use iPhone 13 Pro with Lightroom Classic???? -- JCW2

Just in case there is anyone with an iPhone 13 Pro (or 14 Pro) here, I found some answers:

Apple evidently makes it very difficult to see the lens distortion in its ultra-wide (and probably selfie) cameras.  In order to find out, I installed Lightroom Mobile on my 13 Pro and learned how to sync to my desktop through Lightroom Classic. I also purchased RawDigger "Research Edition" and installed it on my Desktop. My immediate goal was to check the real raw images generated by my own camera for lens distortion. Although I'm still a newbie on RawDigger, and there are still a few uncertainties indicated below, here are some interesting results.

I shot a flat scene with LrM on the Ultra-Wide lens of my 13 Pro in HDR mode . It stored two files -- only one gets stored if not in HDR mode. The first download below is a screen shot of a tiff file saved by RawDigger of the file stored by LrM as "APC_0018.dng":

Second is a similar screen shot of the one stored as "APC_0018-hdr.dng" -- I don't know why this one has a pink cast:

Final one is a screen shot from LrC of the file stored by LrM as "APC_0018.dng":

Evidently the first image has not had (any?) lens corrections applied and shows rather extreme curvature toward the corners from distortion in the ultra-wide lens. Interestingly this curvature is gone from the other two images. In line with that, the EXIF data from the first file reports
"Opcode List 3 WarpRectilinear2, FixVignetteRadial", whereas the second file shows only
"Opcode List 3 MapPolynomial."
I guess the former are the opcodes stored for lens corrections, which are evidently automatically applied by LrC (and by LrM on its own display), and the latter shows why LrC does not report any lens corrections applied -- they had already been applied in camera. -- JCW2
