Quality difference Native vs 'other'

Hi

Not sure my title here is the best but I am wondering about the theoretical quality difference between native third party streaming apps:

Why should Tidal sound better than Qobuz/Deezer assuming they are streaming the same quality. I am thinking Tidal is better because it is 'Naim' rather than Chromecast? Is it processed better or something.

What advantage do the inbuilt Chromecast services (Spotify / GPM) offer over say Deezer which can be steamed using chromecast but is not inbuilt. Naively if you select GPM or Spotify just seems to open the respective GPM/Spotify app - is it just a convenience thing?
