I wouldn't know what a marked improvement would look like - to me, all the screens with 300+ DPI look approximately the same, and the reason to upgrade was always either the build quality or new functions, like touch controls, flush screen, frontlight, or tactile buttons.
I imagine you could find some differences by laying the different readers side by side and comparing the letters under a magnifier, but not with the naked eye.
Here's a couple of photos of my Era - the resolution of my camera is low, but you can see the contrast and sharpness for yourself. If they aren't good enough for everyday reading, then I don't know what is.
