Percentage of mp3 vs FLAC on Tidal?

Hi all,

I recently discovered that on my Squeezebox app I can tap on the artist and album title while the music is playing to see what the source file is and I'm finding that there is a much higher percentage of mp3 music that is streaming than I had expected.  For the price I'm paying I was assuming that everything was at least redbook CD quality but apparently not.

Does anyone know what the approximate split between mp3 and FLAC is on Tidal and if any of the other services are pure and 100% FLAC if you pay for their premium service?

Feeling a bit cheated at the moment, thanks...
There are no mp3's on Tidal to my knowledge everything I stream, and I use it almost constantly are flac. My Aries Mini always shows the file type and sampling rate and its always flac 16/44.1. This is with Tidal premium, I have no experience with the non-premium version.
Definitely premium I'm paying $20 Canadian a month - try The National - Cherry Tree let me know what it reads for you...
the Advanced Settings on my Sonos Connect offers the options of Uncompressed, Compressed, and Automatic    I believe the Automatic uses compression when the signal is weak
Audiojedi, If you're subscribed to Tidal HiFi ($20/month) you should be getting cd quality or better.  If you're subscribed to Tidal Normal ($10/month), you will get mp3s.  Which are you subscribed to?
