Yes, there are eInk readers that have this feature.

The Kobo has a night-mode hack and Coolreader includes one too. I wonder if it would make the front-light more usable in very dark environments. I don't think it's that big a deal to implement. I have it on a Nook ST in Coolreader, but without a front-light, it's pointless.

I think it would cut way down on any color/shadow blobs that might exist. I've tried in the past to use CSS to create a book with this night mode for my Kindle Touch, but Amazon's FW either overwrites or ignores a black background turning it white. I don't remember what it did with the white text. I haven't tried this in at least a year, but I doubt they have changed the FW to allow it.
