I can see the value in flipping modes depending on strong ambient light vs darkness. Smar phones are difficult to see in bright sunlight, and would benefit from reflecting ambient lighting.
The reason unlit color screens usually look darker under light is that they need a filter. Each pixel is going to have a red, green and blue filter that when combined together filter out about 66% of the light before the liquid crystals darken the image even more. I have an original Gameboy Advance and you practically have to be in direct sunlight to play on it. But an original Gameboy is much easier to see since it reflects closer to 80%, maybe even 90% back where the pixels aren't darkened.

Hopefully quantum dot technology will make it way into unlit LCD's. Those don't filter, but rather change the light into a new color.
