Tidal HiFi Test - how representative?


To anyone who has taken the Tidal HiFi Test and also subscribes to Tidal HiFi, how representative of actual sound quality is the HiFi sample compared to what you hear as a "premium" subscriber? Are the differences between the A & B samples used in the test indicative of the improvement in SQ subscribers enjoy?
The enthusiastic Tidal advocates posting on A'gon have certainly got me curious.

Ghosthouse, I believe the test is just a sample to get the listener to hear how Tidal will sound through their system. I'm sure it's a premium signal to show the best that they have to offer. I didn't know about the test either, but I can sure hear the difference between Tidal and Spotify. Try it out. I went premium without thinking about it.
I just looked on my computer and when I play a selection, the HIFI indicator down by the volume control enables, or come on, so premium is HIFI.
Thanks, A$280...I've been trying to avoid downloading yet another program so was hoping I could get a clue about Tidal sound quality from the test samples they provide. The test doesn't require downloading anything. It is NOT an alternative "test system" to the actual Tidal streaming product.

Second point: I might be confused, but when I look at the actual Tidal site (not the HiFi Test screen; see screen at link below) - it looks to me like Tidal Premium is the low cost $9.99/mo option designed to compete price-wise with Spotify, while Tidal HiFi is the high quality uncompressed/lossless option that costs $19.99 per month. So from this, it seems Tidal Premium is definitely not Tidal HiFi. See screen at link here.

Let me know what you think. Thanks. (I do note 30 day free trial)
Love Tidal but I use it exclusively with the Roon Music Server. Amazing, simply amazing. Sound quality is excellent, access to what I want to hear is wonderful and I have noticed no playback delays which is probably due to the Roon server handing those things? Try this combo and you wont go back.
Ghosthouse, I see where you're going with this. Since I signed up for the more expensive plan right away, I don't know how the two plans vary from one another since I'm always hifi. Tidal hifi is streamed lossless, which they claim is CD quality, the way the artists intended for you to hear it. Tidal premium is restricted to high quality, which means the max quality will be AAC 320 kbps.
