Often rely on iOS showing the TV show name in the grid view to differentiate different TV shows when there cover art for a show is irrelevant.
Now in iPadOS26 it seems that information is no longer displayed in the grid view.
So you cannot easily differentiate between TV shows unless the cover art makes that possible.
What would be nice is a way to AtomicParseley or some other tool create the cover art from the metadata of the file.
