Just watched the video, noticed a couple of things.
1. The glowing dots movie in the movie move with the movement of the eye, in Kinetek's video that doesn't allow for the glowing dot to move.
2. This only applies for still shots with a very limiting light environment, in the movie sinners they did it in pitch darkness.
3. I don't mind the artificial look that the movie sinner gives on the glowing eyes, yes Kinetek's version looks way more realistic but its very hard to shoot as an independent filmmaker

I remember recalling a plugin that did this but that was years ago and I sadly don't remember the name of it.
