While this is true of some films, with others it is an illusion created by overscan. The "black bars" are still there on the disc, but are not in the displayed image because they are "pushed off" the screen.
(For that matter overscan makes it almost impossible to "measure" aspect ratio on many sets. Just grabbing a ruler and checking the displayed image doesn't necessarily tell you what's encoded on the disc.)
