I for some reason recall at one point WhatsApp’s encryption was actually an audited implementation of Signal’s encryption. But that is so long ago that I doubt that holds much weight now ¯\_(ツ)_/¯
Even it they (WhatsApp) still provide reliable E2EE, they have lots of metadata that is not encrypted, and that they actively share with their “advertising partners”.
