Kindle Print replicas can be okay but they are basically just PDFs. It's still faster to flick through a book than a PDF. If a non-print replica Kindle textbook has equations it's generally done with images and looks really bad, makes the book really big in size and slow to navigate, the equations can't reflow and so are usually noticeably different in size at every font level.
