24k is industry standard because of tradition. Nothing more.
It has nothing to do with what the human eye can perceive. It was settled on as the standard because it was the minimum fps that provided smooth motion. Any lower got too choppy, and any higher was pointless because the projectors and technology at the time simply had no use for more visual data than that.
The reason it sticks around (and the reason I personally prefer it) is because we’ve been seeing it for so long that changing it is jarring. Almost in an “uncanny valley” kind of way, you watch a film at 60fps and something just seems off but you just can’t put your finger on it. Its almost too crisp.
We are so baked into the look of “cinema” for so many decades that it’ll take time to adjust.
Tl;Dr - 24fps looking better is subjective. But its prevalent because its all we’ve known for literally most of cinema history.
