You also have to take into account new LMS versions default to play
remote sources -5 dB softer ?

And other affects I wonder how streaming services really do stuff ?

It's is proven that under controlld circumstances humans can't spot a
properly made 320kbps encoding from lossles . Anyone here participated
in archimago's internet test of this knows ?

But it can be some more variable at work on a streaming service ? Like
som volume equalisation that is not transparent .

It migth not even be the same master as your own file ,it migth be some
horrid * mastered for iTunes * version it migth not even be 320 Kbps but
some old encoding from the past if you taste is eclectic enough .

It migth actually be interesting to test if streaming services do fail
in sq even if the really should not  ? And if so wtf is up then .

It can be hard to do , even if you turn off LMS -5 dB trick on streaming
sources and line up well known tracks and your own version using triodes
spotify ( where you can turn off spotify's volume normalisation ) . Even
then it can be hard to be sure you don't compare apples with oranges .

And differences may only show up on some material depending on streaming
services ?

I have not done this with any scientific rigor ( it's virtually
impossible ). My feel is that it can be different sometimes :/ I've got
some spotify track being virtually identical on some occasions ? I
suspects his is true most of the times ? But it's hard to either prove
or disprove .

My own conclusions is that this is not a matter of lossles vs lossy
there something else at work that I can't quantify and that there is no
substitute for your own files .

If you,investigate the services that supply lossles I would not be
surprised to find differences there too ?

Do any off them controll the source material or do they just use some
automated service for the labels to upload their stuff ?
I suspect the latter as a service has million of albums and just pushes
what labels put up and actually do not have any quality controll
whatever they call thier service ?
