I think it all depends upon your connection bandwidth. When my connection went from a DSL line that posted ~3.6 Mbps to a fiber optic one that posts ~250 Mbps I did notice an important sound quality improvement with Tidal streaming. This surprised me. And even more importantly, I no longer run into drop outs and tracks stopping spontaneously.
I believe the optical thrust is to get galvanic isolation to remove electrical noise that could be feeding into your DAC. I guess that might be good, regardless, but I can only guess, since I haven't tried that yet.
