Hi-res streaming v. hi-res download

A query prompted by Gramophone magazine's digital publication guide to hi-res audio, just published: all else in the playing system being equal, would we expect the sound quality of a hi-res download purchased from (say) Qobuz be identical to that of the same track streamed from the same source?
Sorry if this is a dimbo question, just interested in what if anything the difference might be and what would cause it. I have Qobuz Sublime+, by the way, but don't buy downloads from them.
Thanks.

 

Interesting yes the downloads are definitely better
But don’t ask me to explain

 

If the streaming service allows you to stream at the same bit-rate as the downloads are encoded at, then it should sound the same. However, not everywhere allows you to stream at the high quality rates.

I use Deezer to stream music, which allows 320kbit/s streaming and I'm pretty happy with that quality .
