I assume you are being sarcastic
Let's just say that amazon cannot even make their own software render azw3 the same across devices. They use completely different render stacks on different devices, you can get some idea by downloading the Kindle Previewer and looking at all the frameworks it bundles. And I wont even get into all the internal idiocies in the KF8 format design that it took forever to reverse engineer.
Still, KF8 is better than MOBI
