The only other thing I can think of to try is set the page-progression-direction.

To do that, if your spine element in the OPF is:

<spine toc="ncx">

Change it to:

<spine toc="ncx" page-progression-direction="rtl">

If that does not work then I am out of ideas.


(Based on your original statement, "But the pages still turn from left to right", this is all about changing the page turn direction so that you can tap the left side of the screen to advance and the right side to go back. This metadata has nothing to do with the direction of text on individual pages.

And just to verify: You are trying this out on your Kindle? I don't think that calibre's e-book reader pays attention to reversed page turn direction in books.)
