If you had used another eInk device you could tell. I did pick up a Kobo Libra Color as well and while I like it there certainly is a noticeable grain and contrast loss compared to my B&W devices. It's just a little less sharp and requires more light to read from. For people just reading novels I think the color screen isn't totally worth it. The Libra Color does finally have a decent CPU compared to prior models so it is nicer on that front but I don't think it's worth it for everyone.
