Assuming it is connected in a basic way, that is Network to Melco to Streamer to amplification.
Set up a playlist and set it playing.
Unplug the ethernet lead from the Network to the Melco. It is now isolated from the Network.
Ok you cannot control it (except maybe handset into the streamer). But is the sound noticeably better?
In this way you have isolated the home network.
I have tried this and cannot notice a difference. There may be various reasons for this. One might be that my Network may not be significantly noisy.
I also thought that the transformer inputs to the Melco were meant to trap most of the noise.

I presume you have set the Melco to fixed IP (on the front panel) rather than DHCP. If I disconnect the Ethernet cable when the Melco is set to DHCP, the music stops playing after a while.

If you don't hear a difference, it could mean (as you said) that your network isn't injecting harmful noise into the Melco via the Ethernet cable. Another possibility is that your streamer is filtering out any such noise.
