How/where are you seeing this list?
TV app on computer.
Less than 10% of my movies have an “Unknown” director.
Generally, it’s present for the same kinds of movies/bundles. Very apparent when I sort by purchase date: Hitchcock bundle, Star Trek Bundle, Aubrey Hepburn movies, Neil Simon Bundle. Not all of them in each of those groups, but a lot (plus a bunch of other randoms).
I really dislike how they don’t have the ones you bought listed as being in 4K.
Yes, you would think they would show it right there, instead of “HD”.
In the TV app menu on macOS and iPadOS, under Library there is a 4K HDR section. There is not currently one on tvOS but it seems there will be one in the revamped TV app when tvOS 17.2 is released.
On the mac you can also make a smart playlist with a 4K filter:
Even in our receipts it only says HD 🙄 Yeah the 4K HDR is nice but doesn’t give a count as to how many we have in there.
