Yeah, I wasn't clear on the versions.

At night, I have to use level 7 on the backlight for comfortable reading without any other lights on. It's noticeably blue to my eyes at that setting. I get that Amazon's trying to make the display look whiter in normal light, but I (and I think others may) place more value on a warmer backlight for nighttime reading. Outside of vacations and doctor appointments, bedtime reading is my most frequent use case.

This is much needed.

The Marvin e-reading app on iOS can change the screen color temperature to adjust the blue level, which helps with bedtime reading.
