This is simply not true. I have seen many valid EPUB that pass epubcheck but failed Amazon conversion. This is just on top of my head.
- Multi-part dc:title. Amazon just error out when multiple titles are present.
- Out-of-order TOC. This is discourage by EPUB spec, but it is allowed. Previously was rejected entirely -- now just get a blank TOC instead.
- Didn't get time to investigated this much, but it seems that books in languages not supported by KDP/Amazon themselves are (or were) being rejected.
Not to mention that EPUB spec require the file to either be in UTF-8 or UTF-16 so Amazon's default assumption of CP-1252 doesn't make sense in this context either (I know the reason why Amazon do this but this does not align with EPUB spec)
