I also use Qubuz lossless (who started out lossless) for some time as Spotify have been promising FLAC for years yet didn't do it, other options are Tidal & Deezer both do hi-res, I also have a fair bit + of ripped FLAC on an external drive - Whether lossless makes any difference does depend on your system, but I've enjoying HQ music since a child as my dad did hi-fi (reel to reel) since the 1950s so its in my blood - I use NAD Pro amp & at moment Q Acoustics Concept 30 speakers, I suppose I've had better systems but hearing not what it was but I can still tell distinct difference if things are not right.
Apple in the past were dodgy about their stream quality in the past so never bothered - If something wasn't recorded above the standard 20-20,000 hertz & db range, IMHO you cannot get back that wasn't there (as in hi-res) in the first place but some new recordings benefit from higher resolution but often its better mastering, however human hearing in adults is not 20-20,00 hz anyway so...I still have some recordings done in the 1950s that put some new over engineered recordings in the shade - Switching between local; FLAC & streaming is simple now & done from my phone or pad now, seamless.
