There are any number of ways displays can show 24fps original content. For years the use of 3:2 pulldown was commonplace, but this introduces judder which is not a good thing.
Early TVs which properly handled 24fps content would often operate at 72 or 96hz. Then they would replay the same frame 3 or 4 times. 3:3 or 4:4 is what is is typically called, but it's just reflashing the same image several times on screen. This is actually similar to what theaters do as most (I believe) double or triple flash the same frame of film, when they use film projectors. Most are digital now.
Now with 120Hz+ displays, you will often get 5:5 display of 24Hz sources and 2:2 display of 60Hz sources. So, you get a true one-to-one conversion of the image.
This still isn't a guarantee, and you have to look up one-by-one which displays properly display 24Hz material at a frame rate which is directly compatible.
Samsung seems to be marginal to weak with many of their displays unfortunately. So, my expectation is that this is not going to be dealt with properly. If you have any motion correction, then you may be able to clean up some judder effects, but that would be determined by the controls you have. I typically see the impact most obviously with the text scrolls during titles and work to clean that up as much as possible, without adding any of the nastiness that CFI can introduce (soap opera effect).
Since manufacturers rarely tout properly 24fps support, you really have to go with reviews to see which ones handle it the best. I have been calling out 120hz for years with front projection. 3D often uses 144hz in front projection with a triple flash to each eye (72hz) for solid quality.
