P: Google Pixel 7 Built-in Lens Profile is applied twice, resulting in lens distortion

The Google Pixel 7 over-processes the camera images, making them artificially sharp and cold, which can sometimes ruin the results.
So I tried using RAW files for shots that could have been good but were badly ruined by the processing. However, there was a problem with the RAW files as well: lens distortion, which is not present in the JPG files, is quite noticeable in the Camera Raw processed RAW files.
At first I suspected that the Built-in Lens Profile was not being applied, but it seems that the Google Pixel does some processing on the RAW files as well, and the profile is already applied to them. RAW file processed in Capture One with zero lens distortion correction is in fact already corrected and has no distortion.

PXL_20241017_060725238_RAW_CameraRaw.jpg - RAW-file processed by Camera Raw, has lens distortion;

PXL_20241017_060725238_RAW_CaptureOne.jpg - RAW-file processed by Capture One, no lens distortion added (correction slider at 0).

(Google Pixel 7 RAW-files are so strange that "The attachment's pxl_20241017_060725238.dng content type (image/dng) does not match its file extension and has been removed")

Is there any way to disable the Built-in Lens Profile in Camera Raw? Or somehow remove it from the RAW files captured by the camera?

Best regards.

Thank you for your replies.

The process for these photo is like that...

0. Photo taken by default camera of Google Pixel 7 smartphone with JPG+RAW option enabled.

For PXL_20241017_060725238_JPG.jpg that is basically it, it is JPG produced by the smartphone itself internally, default camera application.

For PXL_20241017_060725238_RAW_CameraRaw.jpg:

1. RAW-file transferred to PC from smartphone;

2. It is opened by Camera Raw 16.5 (Photoshop);

3. Built-in Lens Profile is applied (along with other basic settings of RAW-file import to Photoshop), lens distortion is added by it (it could not be turned off);

4. Image is saved.

For PXL_20241017_060725238_RAW_CaptureOne.jpg:

1. RAW-file transferred to PC from smartphone;

2. It is opened by Capture One (3rd party software);

3. Lens correction is reduced to 0 in Capture One setting of import, providing the correct image, with lens correction done the right way by smartphone initially;

4. Image is saved.

So it seems that Google Pixel 7 adds correction to RAW-files themselves and saves Built-in Lens Profile after that (which is already applied to the RAW-file).

I will try uploading the PXL_20241017_060725238.dng file again, but it will probably result in the same error... Yes, that did happen:

The attachment's pxl_20241017_060725238.dng content type (image/dng) does not match its file extension and has been removed.

Even though that is .dng file produced by the default camera application, it seems that Google Pixel 7 RAW-files are strange.

~~I did change the extention to .log to prevent that (I am not sure which solution is the best, I can upload it elsewhere).~~ Did not help... Ok, I hope it is ok to paste a link to Google:

I did try Open Camera application on Google Pixel 7 too, the RAW-file produced by it is different, but with the same lens distortion problem.
