I have said so -- and I still think so. But remember that perception tends to be very personal. As far as I know, noone knows how far there are individual variations in iLiad units: I may have a darker ePaper than average. But how do you decide?

But I just read several responses of iLiad/Sony Librie/Junke V8 owners and they all told that only iLiad has almost white screen.

My reaction against the 'white' iLiad screen came about precisely because I've seen photos like this -- I can't fit them to the screen I have. I suspect it may be because the camera adjusts the white point, or does some other image enhancement that makes the photo valueless as an absolute measure of grey value.
Here's a photo of my iLiad, showing a PDF document, together with a standard IT8.7/2 target. The important thing to check is the greyscale band. The 'whiteness' of the iLiad screen seems to be around 80% (very rough eyeballing and mental calculation).
Here's another photo of a book page with the same target. The whiteness of the bookpage is very close to white -- I think above 95%. The book is from the 1890s, and is printed on toned paper, so it is slightly lower in tone that most modern books I buy except paperbacks, which are still lower.
(I see there's some vignetting from the lens setting I used so compare the page at a point near the target point of reference.)
