Using RT 5.8 on Ubuntu 20.04.
When I open a .dng file created by my smartphone (OnePlus Nord), RT does not show the quick image info like speed, iso, focal length etc. for that file.
But I can see that these values are inside the .dng file if I use exifprobe command on Ubuntu. The Metadata tab of RT also seems to omit these values.
A sample .dng file is attached. Also attached is exifprobe output.
Quick image info works with other raw files like .NEF or .NRW
