Will upsampling of new DAC make lossy sound as good as Lossless

A question :

With most of new DAC’s using their upsampling make a lossy Spotify like file as good as a cd quality .

Most of the DAC’s I see move every file to a very high sampling rate and do a lot of behind the scene adjustments.

will this “ fill in the blanks “ for lost data and make it good as the original?

Full disclosure - I have more invested in digital than I had originally planned, but the rewards are there. Yes, I prefer files on my NAS or streams from Qobuz, but even Spotify is now fully satisfying for listening.
