I actually want eye-searingly-bright whites for movies, but interfaces for TVs ... shouldn't use 100% luma.
100% luma is going to be "the brightest object shown in all of your media collection" which is probably the sun. Since on my computer monitor, 100% luma is usually used by UIs to represent a blank piece of paper, I toggle the brightness on my monitor when watching a movie.
