Yes. Unfortunately, that's sort of a red herring. Most email clients show the "pretty text" of the From (the display-name ABNF construct) if it exists, and actually *hide* the actual address (the addr-spec ABNF construct). Putting as much value on RFC5322 From as DMARC does follows conventional wisdom, but I believe that wisdom is flawed. Of course, that speaks to the advice you want to give: tell UIs that they should show the From addr-spec to users always. But be clear about what you're asking for: you're not saying they should do it because it's objectively "right"; you're saying they should do it because it helps support the decision that DMARC has made.
