I think they are focused on tablets based on the popularity of them. Blue light exposure in the last few hours before bed is detrimental no matter what the source; tablet, ereader, or even ambient lighting.
That being said, I don't think you get quite as much total light exposure (and therefore blue light exposure) from an ereader as compared to a tablet. I tend to turn down the light on my Kindle at night to match the ambient lighting. I am hopeful that the rumor of inverted mode coming to more Kindles is correct because that should help reduce total light coming off (and therefore blue light).
There is another thing you can do related to blue light to improve sleep. While blue light exposure just before bed is detrimental to sleep, it can help improve sleep with lots of blue light exposure during the day. So one thing you can do is head outside with your ereader and take a short walk and read!
