Not sure there was any noticeable difference but not a scientific test. What I did find was Qobuz within Wiim App was gapless as was Qobuz App on my Ipad but when I used Chromecast from Qobuz App then it wasn’t gapless - tested using old standby of Dark Side Moon track 1 to track 2 transition.Was there sound quality difference between chromecast 24/96 vs wiim app 24/96?
Anyway I prefer to use Qubuz within WiiM App rather than native Qobuz App on iphone/ipad since then I don’t need to keep my iphone/ipad running to play music.
