Missing QuickLook thumbnail for supported (Canon R Series) camera RAW file type (Sequoia)

Is anyone else experiencing this issue ...

Canon's RAW file formats have been supported by macOS for a number of releases (see Digital camera RAW formats supported by iOS 18, iPadOS 18, macOS Sequoia, and visionOS 2 - Apple Support (CA)). After upgrading directly to Sequoia 15.1, I noticed that the QuickLook thumbnail was missing for such files:

It should look somewhat like the following example (which uses a custom Finder icon for the thumbnail in place of the QuickLook thumbnail).

Is this a likely oversight in Sequoia or could it be the result of Canon not providing a timely update that conforms to Sequoia's QuickLook app extension API for thumbnail generation?

Thanks for the replies. I experienced the problem with the CR3 RAW file format used by the EOS RP and EOS R5. Both cameras have been supported by macOS for some time.

Thanks that's very interesting. I wonder what's different in my environment. I'll try copying a test CR3 file to another user account on the same machine.

I copied a test CR3 (R5) file (via macOS Drop Box) to a different user account on the same machine. The thumbnail image is still not visible in Finder.
