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.

Hey 280...we like the blues and blues-derived R&R a lot. Here's a link to a Bruce/Moore version of White Room if you haven't already heard it...

ALSO - you can type the names Gary Moore Jack Bruce (no ampersand) into the Spotify search box and come up with quite a few good things to hear.

Carrying pencil and paper to make notes about music heard while mowing...good on you. Glad to read about someone else with a music jones.
There are 33 albums by Gary Moore on Tidal. Is Ball & Chain an album or a song?
$280 if you like blues look these up on Tidal:

J Roddy Wallston and the Business eponymous album very unique sounding rockabilly blues with a touch of Leon Redbone.

Danny Kroha Angels Watching Over Me stripped down country/gospel blues with a hard edge.

Cheers,
Jon
