To me when I read this, it gets translated to...
At an unrealistic presentation speed, I see something unrealistic as being more realistic. At higher presentation speeds that get closer to reality, I see something unrealistic as being less realistic.
But, I understand what you mean.
For people that watch a lot of 24/30 FPS video, they expect to see animation and presentation artifacts (juddering/stuttering/etc.). And thus things the lines become more blurred with regards to what is real and what isn't. IE - your mind is already making excuses for what it sees in an attempt to make it fit what it expects to see.
When they see something that is presented as closer to what their eyes see in reality, then it "feels" like something is off. So at higher framerates the presentation gets that much closer to what your eyes expect to see when it seems the world in motion (moving objects or just moving your eyes around), there's less things for your mind to accommodate and thus unrealistic things now have less reason to exist.
This was similar to the uncanny valley that a lot of people experienced as HD content started to appear as HD TVs started to replace SD TVs. Things were too sharp, too well defined, they could now see the makeup actors wore, they could now see the lighting in shows and film was overdone, etc. This also happened with a lot of people with the move from 4:3 TVs to 16:9 TVs. For many years a lot of people insisted on 4:3 content stretched to fit a 16:9 screen because it looked "wrong" to have black bars on the sides. IE - a filled screen looked more "realistic" to them even with the stretching than a 4:3 correct presentation with black bars.
As I never watch 24/30 FPS anything anymore if I can help it, 60 FPS is the new normal "unreality" for me. It's less divergent from how the world around me looks and operates, but still enough that it's not quite as smooth as reality. So there's still a bit of adjustment my mind makes to make it seem closer to reality and that takes along everything else with it.
So now, when I look at anything 24/30 FPS, all I see is a horrible mess where almost nothing makes realistic sense. Hobbits included.
Unfortunately for me, this means that without some form of good interpolation (plenty of tools for this on PC that are much better than TV interpolation in general), 24/30 FPS film and television look downright wrong and nasty.
End result? I hardly ever watch film or television shows anymore, because they all just look "wrong." The ones I do watch, I try to find a digital source and then convert it to 60 FPS.
