But is IFE presentation the same on the 787 (as on the older 767s)? Ie, have the screens not been improved? Do they still say "edited for screen format" on just as many movies on the 787 as on the older 767s?

The screen quality and aspect ratio, as well as all the movies saying they were "edited for" that screen, seemed extremely out of date on the older 767s I flew on LAX-(LIM)-EZE and back last month.
