LR not rendering S22 Ultra photos correctly (this is NOT the LR In-App camera bug)

I have a Samsung Galaxy S22 Ultra (Android 12).

Lightroom Mobile v7.2.1.

Lightroom (Windows) 5.3

Lightroom Classic 11.3

• I take photos on the phone with the stock Samsung Camera app (v 12.0.01.62) in normal as well as PRO modes, and also Samsung's Expert RAW app (v 1.0.01.1).
• The photos are generally in HEIC format, but I also use RAW (DNG) and JPEG.
• The issues described below are found with the HEIC photos, not DNG or JPG.
• I import photos to Adobe Lightroom Mobile on the phone.
• The photos as displayed in the stock Samsung gallery look 'correct' / as expected.
• When they are displayed in the LR Mobile gallery they are too bright and also appear to be the wrong colour balance.
• When I open an HEIC image from the LR Mobile gallery the image then 'resolves' and matches the way it looks in the stock Samsung gallery (i.e. 'correctly'). This does not then translate back to the gallery view - the image still looks wrong in that view.
• Moving to the Windows PC and Lightroom (v5.3), the photos' appearance matches that seen in LR Mobile - i.e. too bright and the wrong colour balance when displayed in the film strip.
• This is where it gets odd
  • With LR v5.2, when opened to a single image view the image 'resolved' after 3-5 seconds and then looked correct.
  • The images in the film strip remained incorrect.
  • With LR v5.3 the images remain too bright / incorrect colour balance all the time, both in the film strip and when opened as the main image - they do not now 'resolve' to the correct look.
• I also use LR Classic, where the photos are synchronised via LR Mobile's albums
  • In LR Classic 11.2 the photos looked correct in both the gallery and individual formats as soon as they are opened.
  • With LR Classic 11.3 however the behaviour has become rather odd - they change between incorrect and correct in an on/off fashion - see attached screen recording. 

I hope that is enough information but if you require more let me know.
