I think I would be more inclined to get it if it supported 2.5Gbs or preferably even 10Gbs.

I have Infuse app for playback on my Apple TV, and recently tried to play, from my local nas on 10Gbs link, some 4k ProRes footage. I forget if it even has the decoder for it, but just the bandwidth wasn’t even enough to play that. Honestly also from experience, playing from local network a 80GB BD remux is also kinda so-so. Random hiccups for me during normal playback. And just completely unreliable fast forward/backwards seeking.
