Hey and welcome to the Forum (:
Simple answer: No.
Long answer: Dedicated Servers and so called “Listen Hosts” only differ in the fact, that the Listen Server is also a Client.
You need replication for both, but the Dedicated Server can be hosted as a standalone on some V-Server without any Client being connected.
The Listen-Server, on the other hand, is a Client himself. So the Client who’s playing is also hosting the Server. If this Client closes its game,
the Server will shut down. Dedicated Server also needs no UI (no player, no UI) and has not PlayerController that could be retrieved with
GetPlayerController0 on Server site.
But the main question about the Replication avoidance is simply NO. Both require the same kind of replication. Only the Listen-Server also needs
the Client aspect. In a Dedicated Server, you still need to take care of replication for Animations, Bullets, Interactions etc.
