From my experience, Flipping Book works well for SEO. It provides HTML 5 content which you can integrate into your website. This will help with the time spent on the page and with content as well.  Therefore, what I would suggest is to implement the HTML versions and then offer a download button for the PDF. I think the users will enjoy this change and it will be good for crawlers as well. You can see an example of our implementation here -> https://www.catalog-az.ro/. Let me know if my answer helps.
