I was thinking precisely that; I figured it'd need to be subtle and just-above-subliminal to have the most effect.
Completely agree about the 24fps-vs-60fps thing. I think this is a combination of both the fact that the lower framerate is less visual stimulation, and that I'm used to both the decreased visual stress and the overall more jittery aesthetic of 24fps.
Regarding >24fps, I think how it's used is critical.
I remember noticing https://imgur.com/gallery/2j98Y4e/comment/994755017/1 (yes, a random imgur gif - discovering that imgur doesn't have an FPS limit was nice though). I think this particular example pushes the aesthetics ever so slightly, but still looks pretty good.
I don't know where I found it but I remember watching a 48fps example clip of The Hobbit some time back. That looked really nice; I completely agree 48fps is a great target that still retains the almost-imperceptible jitter associated with 24fps playback.
To me the "nope"/sad end of the spectrum is motion smoothing. I happened to notice a TV running some or other animated movie with motion smoothing on while in an electronics store a few months ago... eughhh. It made an already artificial-enough video (I think it was Monsters Inc University) look eye-numbingly fake (particularly because the algorithm couldn't make its mind up about how much to smooth the video as it played, so some of it was jittery and some of it was butter-smooth). I honestly hope the idea doesn't catch on; it'll ruin kids and doom us to having to put up with utterly unrealistic games.
But I can see that's the direction we're headed in: 144Hz LCD panels are already a thing, and VR has a ton of backing behind it, so it makes a lot of sense that VR will go >200Hz over (if not within) the next 5 or so years.
The utterly annoying thing is that raising the framerates this high almost completely removes the render latency margins devs can currently play with. Rock-steady 60fps (with few drops below ~40fps) is hard enough but manageable on reasonable settings in most games nowadays (I think?), but when everyone seriously starts pining for 144fps+ at 4K, it's going to get a lot harder to keep the framerate consistent - now that we've hit ~4GHz, Moore's law won't allow breathing room for architectural overhead as has been the case for the past ~decade, and with current system designs (looking holistically at CPU, memory, GPU, system bus, game engine) we're already pushing everything pretty hard to get what we have.
So that problem will need to be solved before 144fps+ becomes a reality. A friend who has a 144Hz LCD says that going back to 60Hz just for desktop usage is really hard because the mouse is more responsive and everything just "feels" faster and more fluid. I'm not quite sure whether the games he plays keep up with 144fps though :P
On a separate note, I've never been able to make the current crop of 3D games "work" for my brain - everyone's pushing for more realism, more fluidity, etc etc, and it just drives things further and further into the uncanny valley for me, because realtime-rendered graphics still look terribly fake. Give me something glitchy and unrealistic in some way any day.
