There is a DIFFERENCE between a "dual mobi" created by Kindlegen, via KG through the CL, or through Previewer, and the "dual mobi" format (AZW) that's created by Calibre. They are not the same thing--in Amazon's eyes.
That file was created by official kindlegen app, Calibre was not involved in any way.

I do not want to publish to Amazon. I just want to view an existing file.

If you run kindlegen without "-dont_append_source", then original EPUB is saved into mobi file (together with KF6/8). And modern Kindle Previewer uses that original EPUB data for preview (unlike ebook reading app/device that would use KF8 data). So, previewing files without "-dont_append_source" is cheating because you see not what you actually want to see.

And I don't want to convert the file to KFX, I just want to preview what is already present in file.
