Did you actually try playing it? I redeemed the Bluray digital code years ago, which was only SD at the time. It's showing under 4K in the TV app, and has the 4K badge in the Movies app, but playback is definitely not 4K.
In the iTunes Store, it's asking me to buy it for $7.99 in HD/4K, but if I click "available in SD" that version has the cloud download icon.
