Samsung "Scene Optimizer" and EXIF data

Question

Considering this earlier question Is it generally accepted that "Samsung 'space zoom' moon shots are fake" and that some cellphones (e.g. S20 Ultra) use AI to add features?

Leaving aside the lack of authentication which might leave metadata vulnerable to undetected modification, does Samsung's "Scene Optimizer" leave an unambiguous field in a photograph's EXIF data?

Is there sufficient identification of firmware version etc. that the scope of automatically-applied modifications can be determined for forensic purposes?

Given that every EXIF field can be modified arbitrarily, anyone relying on them for forensic purposes is probably doing it work; see e.g. this answer to "How to detect if a photo's metadata has been changed?". — Philip Kendall, Nov 27 '23 at 13:26
@PhilipKendall, yes, that's why I explicitly said "leaving aside the lack of authentication". — Mark Morgan Lloyd, Nov 27 '23 at 13:34
@RomeoNinov What about it? I don't have one and can't find documentation, which is why I'm asking... — Mark Morgan Lloyd, Nov 27 '23 at 14:34
@MarkMorganLloyd, maybe Samsung add specific value to this tag when AI is involved. I neither have Samsung phone so I can't confirm. It's just a speculation. — Romeo Ninov, Nov 27 '23 at 14:40
@RomeoNinov SceneCaptureType can be found in the EXIF specs on page 69 and page 172 (links via Archive.org) — StarGeek, Nov 28 '23 at 15:42
Most camera specific metadata is very poorly documented, as camera manufacturers don't release this information. To figure out if there is a setting, you can try taking a picture with and without Scene Optimizer on. Then you could try and use exiftool with the -u (-unknown) option and compare the two for a possible setting. Use this command exiftool -G1 -a -s -u -MakerNotes:all file.jpg — StarGeek, Nov 28 '23 at 15:47
@StarGeek Thanks for the reference to the foundation documentation. Neither of those pp have anything about (numeric codes equivalent to) "Scene Optimizer", so I think we have to assume that if use of that feature is recorded at all its encoding is Samsung-specific. — Mark Morgan Lloyd, Nov 29 '23 at 10:31
