pdfstudioviewer (java, proprietary) does display signatures.

It seems this is what you are looking for: Signing ODF and PDF documents with LibreOffice https://kamarada.github.io/en/2020/03/13/signing-odf-and-pdf-documents-with-... TLDR: LibreOffice Draw can open PDF documents and is able to check their digital signature.
