Just tried it and I can't really tell. I unplugged my PS4 and the LAN cable. Then booted the game. It felt subjectively better for some time. Still had frequent noticeable framedrops though. Then I plugged the cable back in and it didn't feel much worse. I unplugged again and could not tell a difference.
Waiting for someone to make a comprehensive analysis of it.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
