I realized that with the markings that were visible through the cartridge door, it was essential that I open up the cartridge, inspect it and clean it if it can be used in the drive. I unscrewed the bottom plate and opened up the container. Immediately, I could see scoring, scratches that glinted because they were deep enough to expose the aluminum substrate of the platter. Oh dear.

Circular scratches fill an area somewhere near where the CE information was recorded, rendering it unusable because any heads flying on this pack would be damaged. I took several pictures looking at the scratches, plus the dark circular area on the other surface which may be rubbing wear but does not show the aluminum at the base.
