Ethernet vs. Wi-Fi streaming

My question is simple…

If you have a very strong WiFi signal to your streamer and there are no signs of buffering are you giving up any sound quality?

I have a BluSound streamer to my Gustard DAC and stream Qobuz/Tidal 90% of time with no issues.  Would a hard lined Ethernet do anything to improve sound quality?  Hope my question is of value and makes sense.
