Is there any benefit to have a wired backhaul for an Orbi Mesh system?

CrimpOn thanks!

The debate I've been reading is that since Orbi already has a dedicated triband that is reserved strictly for a wireless backhaul to communicate with other satellites in the network, establishing a wired backhaul (whether MoCA or true ethernet) wouldn't help any since you won't get any added bandwidth from freeing up that wireless backhaul band and can't use it anyway.

My impression around mesh technology is that regardless of where you go in the home (assuming the mesh is setup correctly), you'd still achieve consistent speeds throughout even at the ends of the home furthest from the router via the satellites. For example, knowing that there are a ton of more factors to consider but for simplicity sake let's ignore for now, if I'm paying for 800Mbps down I would expect to see speeds consistently close to 800 Mbps everywhere I had a connected satellite and throughout the home.
