24 frames per second is starting to look awkward in 4k.

24fps doesn't look any different in 4K than it did at 1080p. What kind of TV do you have? I'd check your judder settings.

I'm an Assistant Editor on the reality TV side. Depending on the series, we shoot in 23.976, 29.97, and 59.98. 23.976 still looks best to my eyes.
