> Motion interpolation or motion smoothing increases the frames per second from 24fps to 60fps

It's pretty common for TVs to have even higher refresh rates these days - my 4 year old mid-range LG OLED is 120hz, for example. Conveniently, 24 evenly divides 120, so when you turn off the interpolation you get perfectly consistent frame times.

As a more general note, don't be afraid to experiment with the settings. If you're watching low-bitrate netflix streams, some of the artifact-reduction filters can be worthwhile, especially on the lower intensity settings.

For watching bluray remuxes however, "filmmaker mode" or equivalent settings is generally the way to go.
