Tidal MQA vs Qobuz hi-res

I’m brand new to streaming. Just got Tidal and Node2i 4 days ago, and i’m in the "comparing to CDs & LPs" phase. I’m noticing a few things. The albums on Tidal are sometimes EXACTLY the same as the CD. But sometimes they are the same master, but a couple dB louder, and thus more compressed/limited. I have 3 CDs of one album that are 3 different masterings (1985,2001,2009). Tidal has the 2001 & 2009 masters available. The 2001 sounds exactly the same, but Tidal’s version of the 2009 master is about 2 dB louder than the 2009 CD.
As for MQA, it seems like the highs are a bit soft and squishy sounding. I was expecting better sounding transients from MQA, but they sound less exciting instead.
I have heard several 70-80’s rock tracks that are simply crushed. I pull out my old vinyl to A/B with Tidal, and sometimes it’s better, and sometimes it’s worse, but the new versions are always more compressed. MQA isn’t worth a damn to me if the dynamics have been squashed.

Qobuz offers different file formats to download. All that I have seen have "CD quality" (16/44.1) as an option with a few lower options (mp3s, I think).

The files you dowload at 16/44.1 will be just that, 16/44.1. However, is that really what it was originally? Is there a possibility that some of those are upconverted files?

I ask because I have seen a few somewhat obscure albums in "CD quality" while I have doubts that they ever made it to CD. I am probably just paranoid, but provenance of streaming files seems unknown at times to me.

I A/B listened to Qobuz HighRes and Tidal MQA.  I didn't hear much of a difference. In some cases, a track would sound better on one than the other, but neither was a clear winner in that department.  When it came to CD quality tracks, there was no appreciable difference between either streaming service or tracks played from my Innous Zenith MKII network streamer.  I settled on Tidal because it has more of the music I like and I get a 40% military discount. 

I use Roon.  My PS Audio DirectStream DAC (DSD) renders MQA and I like the sound.  I placed a Matrix X-SPDIF 2 between the Zenith and DSD.  The Matrix does not render MQA; however, sound quality via the Matrix i2s HDMI interface is noticeably better than what I had before.

In my case, I think my choice of system components had a bigger impact on SQ than my choice of streaming service or the format of the music streamed.
