I'll check later if it's been changed. It seems particularly pointless if it's the same. But I guess then the preview is now then only use for docx upload. Before it the preview download was some sort of dual mobi, at least at one stage. I never ever sent that mobi to Amazon for a Kindle, I just USB transferred it.
Amazon recommended to me that a known "correct" epub2 was the best to upload to KDP and better than docx. At the time, with no change here, the docx uploads stopped working properly because all the page breaks were getting removed. Amazon couldn't figure it and when I said my epub2 was perfect they wrote I should have been uploading that and not the docx. Indeed the KF8 and KFX from uploaded epub (test purchases!) and the mobi KF7 identical results to our locally created one.
So really then there is no preview file being offered. A web view is not a practical proof medium and the so called Kindle Previewer is actually taking an epub2 and converting it and no assurance that it's the same result as a retail Kindle customer gets.
This means there is now no point to downloading a preview when you upload a verified epub2. We run Book Check, Epub Check, test all the links & TOC in Calibre Viewer and also if new styles are used we test on three kinds of real eink Kindle (KF7, and Kindle and Publisher Fonts mode of KF8), Lithium on Android, Aldiko on 4.3" Android, Sony 5" PRS350 and two models of Kobo.
