Let's open another can of worms — are music streaming services providing genuinely lossless audio?

I'm not surprised if they alter original PCM data to add audio watermark on PCM stream to track down which user illegally redistribute it to pirate sites

So, the question really is: Are music services using the same digital music files as you'd get on, say, a CD, or buy from HDTracks, Linn, NativeDSD or elsewhere?

 

On several years ago of Sound & Recording Magazine (monthly magazine published in Japan) there is the article about art of mastering for high-res. They said something like "it is better to hump some audible high frequency for high-res master, and apply more maximizer for CD master" so maybe answer is no.
