I have a few comments unrelated to high DPI that could better the readability, slightly: The indents of the first line of the paragraphs are not necessary as the paragraphs are already spaced vertically. Chose one: vertical separation or indentation, this will reduce the noise of the page slightly (or as I call it: the vibration). Justified text is very hard and I’d generally avoid it where it can’t be controlled (it’s ok for print or where it can be adjusted). There is too much space between words that will form “rivers”, again: noise on the page… You are probably safer with left aligned text. Footnotes could have a different aspect to differentiate from the body text. Smaller? Lighter? Up to you. Finally: the font renders perfectly on my hi DPI screen but I’m not sure about the bold weight; it looks like it’s derived from the book? Is the correct weight installed or is it computed?
