I used KindleUnpack to unpack the azw3 files and then looked at the content.opf in the OEBPS directory to find the watermark entry. KindleUnpack gives me the ebook contents in 3 directories with the majority of the data in a mobi8 directory. The mobi8 directory for the 5 books I unpacked contains META-INF and OEBPS directories, an epub file and a mimetype file. The epub file does not contain the same infomation in content.opf as the content.opf in the OEBPS directory but it does match the information shown for content.opf by calibre.

Again, my suspicion is that those ebooks were either not downloaded from Amazon or the watermark was present before the ebooks were submitted to Amazon. As in the ebook my wife downloaded from Entangled.
I do have one ebook that I downloaded as a freebie from the author and the metadata says "This book was given to Name Withheld (12345678) but that is in the content.opf file wrapped in a dc:description tag.
