For mailboxes that implement DMARC and send reports, Valimail (and Dmarcian I believe) have historically tracked and published that. I'll hunt down that data tomorrow. Off the top of my head, it was about 80% of mailboxes globally (4bn+) properly validate DMARC, and the majority of those send reports, with the notable exception of Microsoft, which is now finally starting to do that. For PSD, I don't think that's implemented anywhere at any major mailbox provider, just in some open source libraries as a test.
