Qobuz and Tidal Cross Data Sharing through Roon?

I have both Tidal and Qobuz but use Qobuz for about 95% of my library. Ie most of the time I select the Qobuz versions for my library. Funnily enough though when I look at the Tidal “My Mix” it looks very much like it’s being informed by what’s played by Roon - which is almost all Qobuz. So, am I dreaming or is there cross pollination through Roon somehow?
