I hear it. In my case, I suspect it is a trained response rather than a mysterious neurological phenomenon. [1] Motion picture sound effects synchronize distant events such as explosions with the sound of explosions. When I am looking at a screen simultaneous audible and visual experience is what I have come to expect based on experience. A delay when watching a screen would seem unnatural.

One reason I expect it is a unique response to images on screen is that I don't find anything odd about the thunder coming well after the lightening in the real world, but a six second delay would be odd in a movie.
