Apparently the study could be replicated (with a neutral expression as shown in the example). Given that, I think it's unlikely that anyone is unaffected.
I have two hypotheses:
a) It may be a kind of hindsight bias. You watched the video in the context of an article on the Kuleshov effect and knew it was the same neutral expression each time.
b) You cannot gage the mood of the embedded scene and thus cannot transfer it onto the encasing scene. The end result is that you are not affected in this instance. But it would not be because of some immunity to the Kuleshov effect itself.
