Huh?? Unlike a video file where higher resolutions result in larger files though improvements in compression technology have kept that size increase down, I can't see how an increase in screen resolution would affect the size of the ebook. I read the same ebook on multiple devices with resolution varying from 360x480 to 2048x1536. What I do notice is the higher resolution devices do better at displaying characters since they can spend more pixels on each character but that has no effect on the size of the ebook. The only way I can see a massive increase in the size of ebook would be adding more images to the ebook. An example would be more comics and manga being published in epub format rather than CBZ/CBR format. Otherwise, I can't see any good reason for the majority of ebooks adding masses of images.
