I don't know if the work's been done yet. It would need to take into account real-world conditions if it is to be useful, since people don't typically sit in a dark room staring at a white document with their iPad cranked to full brightness.
I don't suppose anyone's seen data on the amount of light the frontlit readers put out at low brightness?
