Concerns about sleep disruption are tied to blue light, which can interfere with melatonin production. The white light from the Kindle’s LEDs do include blue light. However, exposure is significantly less than from tvs & computer screens, etc.
Just how disruptive Kindles actually are was hard to pin down. I found lots of contradictory hearsay and few primary sources. I’ll keep looking, but in the meatime, thanks for setting me straight.

Also, keep in mind that blue light exposure during the day is part of the equation as well. Getting outside and getting good blue light exposure during the day can mitigate some the impact of blue light exposure at night.
