Please accept my sincere apologies here — When I checked this the first time, the 44.1/16 FLAC version was Qobuz, not TIDAL. I’m seeing the same in Roon and TIDAL that only the AAC version is available.
I discussed this with the team and we checked with a Canadian account that we have and we think we see what is going on here. With a Canadian account, in the TIDAL desktop application, we see that it does show HiFi. However, when we went to the TIDAL web player with this same account, the quality is only showing as High (aka AAC).
When we look at the data that TIDAL is providing us, we only have AAC for any region where this album is available. The only place where any other format can be seen is with a Canadian account in the TIDAL desktop app. It’s hard to say if the desktop app does have access to a higher quality version of the album than everywhere else or if it’s just a display issue, but ultimately we do not have access to any other version than the AAC version that is being provided to us (and can be seen in a vast majority of regions and players).
You have our apologies for the inconvenience and confusion here! If you have any questions about this please do let us know.
