I think you're right about how non-email messaging clients have
influenced email.

But even in email, Microsoft's Outlook, with its roots as an
intraoffice memo client, has shown only display name as far back as I
know, except when Internet mail comes in with a From header that has
no display name to show. For all its quirks, Outlook is the only
client I can think of that shows the content of the RFC5322 Sender
header, even if it is in the peculiar "x on behalf of y" notation,
which shows display name when there is one and address otherwise.

But we are digressing into a proposal for an Internet Email Client standard.
