I don't see how backlight settings for a truly dark room are relevant here. I've been annoyed by several of my devices being unable to dim far enough, but never in a situation where I would expect to be able to easily read words printed on paper. An office or classroom setting that has adequate light for pen and paper work could be too dim for an LCD at 100% brightness to be comfortable, but almost any device can be dimmed enough for that environment.

Color temperature can also be a problem, but there's a lot of awareness of that issue nowadays. Most operating systems now support automatic adjustment of color temperature based on time of day, plus manual adjustment. Devices that adjust their color temperature to account for ambient lighting are starting to catch on, and I expect they'll be pretty common in a few years.
