Replying to Ski Videos on Smart TVs

Wasn't sure where to post this but I think I'll probably get the best answers here in this forum section.
So recently I bought a 4K Samsung Smart TV and watched the new Faction Collective Edit on the YouTube App. I noticed during fast movements of mostly smaller objects some kind of distortion going on. I'm pretty sure it has to do with the refresh rate of the television which you can basically not look up anymore since Samsung introduced the PQI scale. So my question is: How can I make ski videos look more fluent while watching on the TV? Is it better to turn "Auto Motion Plus" on or of? (it sometimes looked better when turned of which was kind of surprising)
Hope someone is into this topic and has an answer!
