Hello redhonker,
Thank you for documenting the difference with specific photo and MP4 examples.
Microsoft documents the Windows photo “Date taken” property as the date the photo was taken, read from the camera's EXIF metadata. However, I couldn't find an official setting that allows File Explorer users to configure a rule that prioritizes “Date/Time Original” over “Media Created” or independently controls their time-zone conversion.
Because your proposed logic concerns how File Explorer should choose and display media timestamps, the best route would be to submit it through “Feedback Hub” by pressing “Windows + F”. Your feedback will be forwarded to the appropriate team for review and consideration in future updates.
Official Microsoft documentation: System.Photo.DateTaken
