The point would be to get more screen estate and hence a more immersive experience. It's why The Shield was later released in widescreen despite originally being cropped for 4:3. Similarly there's a non-matted full-frame video from Jurassic Park and it's a whole different experience because you see so much more. AI would allow generative fill to create the environment and truly experience the vast space or see the environment even in close-ups. The counter argument would be that frame and composition matter.
