"Free-text" notes (what Okular calls "Inline notes" and "Typewriter notes" and Foxit calls "callout", "text box", "typewriter" notes) are not extracted. I suppose this cannot be fixed (pdftools cannot create these annotations; it can edit them, but will not list them. See https://github.com/politza/pdf-tools/issues/438)?
As an example, I am attaching a pdf with an "Inline" and a "Typewriter" note. Both were created with Okular, and then I added more text using pdf-tools: ex-annot.pdf
This non-extraction also affects, of course, similar notes created with, for example, android apps for annotating PDFs.

Both org-noter (https://github.com/weirdNox/org-noter) and org-noter-pdftools (https://github.com/fuxialexander/org-pdftools) are affected.
For the record, these types of notes are not extracted either by Zotfile (http://zotfile.com/) using pdf.js (https://mozilla.github.io/pdf.js/).
