Looks like Voyager does not support it, and the developer is not eager to add the functionality. This is their most recent comment on the issue, commented an entire year ago:
My official stance on
display_nameis negative, specifically due to impersonation and UX concerns (you can see my full thoughts here: https://vger.social/comment/4447844)While I won’t support showing
display_nameby default, I would consider showing a futureflairby default.I would also support adding a setting to show
display_nameif it was off by default.

I’m not an expert on the whole Fediverse thing. I use Voyager on iPad since it is a clone of Apollo that I used back with Reddit, and I use Boost on my phone since I too used Boost for Reddit. I’m a simple man :)
In Boost it shows as Seam hardware and in Voyager as Steam deck. It’s fine with me since I know what’s going on. May it be a deal for someone that doesn’t know? I don’t think so, but who knows.
