TIDAL HIFI quality not as good as local CD

I have been using Roon for quite some time, with all my FLAC albums and TIDAL HIFI.
Recently, to my surprise, I found out that the same album sounded a lot worse on Tidal in comparison with my local FLAC album. I can see that Tidal is outputting 44-16 and roon shows bit-perfect in both the Tidal streams and my local 44-16 flacs.
As an example, I can pick R.E.M - Everybody hurts (from the album “In Time: The Best of R.E.M.”. In the first 10 seconds it is noticeable that the high-pitch beat (cymbal?) has not half of strenght and depth in Tidal than in my local 44-16 FLAC.
Is it possible that Tidal is upsampling 320kbps mp3 as 44-16?
