16:9 enhancement or 16:9 anamorphic encoding means that on the disc the image is horizontally squeezed to minimise the letterboxing (black bars) above and below the image. This means more of the resolution of the DVD format (720 X 576 = 414720 pixels for PAL, 720 x 480 = 345600 pixels for NTSC) is devoted to the actual film image, rather than wasted on simply black letterboxing. This is a more efficient way to encode the picture because it effectively increases the resolution of the image so it looks better quality.
The sad thing is, releasing a Smileboxed version on SD-DVD would've made better use of the (relatively) limited resolution of DVD, rather than releasing it in such an extreme 2.89:1 Letterboxed format. Even given 16:9 enhancement, the 2.89:1 ratio on the DVD release would only be using about 284 pixels vertically. The other 200 (approx) are 'wasted' on the black letterboxing bars. I don't have a degree in pure math so I can't figure out how many vertical pixels would be 'saved' by smileboxing, but my guess is it would be about 28800, or nearly 9% of the total resolution of the image.
Non-anamorphic discs (which thankfully are rarely released now) waste pixels on huge letterboxing bars (the wider the aspect ratio, the more pixels are wasted on letterboxing, 2.89:1 is the widest image ever released on home video as far as I know), which decreases the image quality. It also means you have to use the zoom setting on a widescreen monitor, which again reduces the perceived quality.

There were only two films shot in CinemaScope 55, The King and I and Carousel. They have both been released correctly formatted on DVD. All other 2.55:1 CinemaScope films were shot on 35mm film without an optical soundtrack, hence the wider than usual aspect ratio.
Smileboxing is only suitable for 3 panel Cinerama films. I don't think it is an appropriate way to show any other widescreen films. They simply weren't intended to be shown on screens with really deep curvature like proper Cinerama screens. Smilebox is simulating the curvature of a proper Cinerama screen (147 degrees). CinemaScope films were never intended to be shown on screens curved that deeply.
