It’s probably motion smoothing causing it to flicker on certain TVs. Why motion smoothing exists on TVs is another question. I guess some people want everything to look like a cheap soap opera.
I've found the lowest motion-smoothing setting makes watching stuff like this far more enjoyable while avoiding the awful soap-opera effect you get from higher settings.
It felt awful to admit to myself since I hated on motion-smoothing for so long, but I simply cannot not see the 24 frames in pretty much all scenes where the camera is panning and background has to move a lot.
