Pocketbook vs Supernote at low light

I currently read a lot on a Pocketbook HD 3. Is there anyone who has this ereader or same display with a Supernote in comparison in the same photo, to see te difference in "medium to low light" situation? Ofcourse, with the ereader front-light off :) As the Pocketbook has a light spread layer, I can imagine the Supernote to have better contrast. Hopefully someone has a way to show that difference.
