Here's what they said about that:

This study had a number of limitations. . . .

However, a number of newer models of light-emitting devices are even brighter than those used in this study. Moreover, in this study, the LE-eBook reader was held at a fixed distance (30–45 cm) from the eye, further from the eye than many people might have chosen (therefore reducing retinal light exposure), particularly for users of smaller devices who may hold the smaller screens closer to the eyes.
Replication under different conditions would be a good idea before Apple and Kindle Fire change the wavelength for their white text backgrounds. But I'm betting the direction of the effect will be as found here.
