Indeed. For bad news, e.g. crime, the (German) media takes great care to mention whether suspects or convicts are immigrants or of direct immigrant descent. Attaching this information to good news is done less frequently but would be required to paint a more realistic picture.
That is news to me. German police and media normally go to great length not to mention names/personal information of suspects (and victims), a crass difference to the US.
Until 2017 this actually was a rule (not a legally binding, just the "honor code") for media, but this got changed after the AfD and other Nazis whined for years that police and media would not "tell the truth" about migrant crimes, "suppress" or "hide" them (https://www.migazin.de/2017/03/24/presserat-aendert-richtlin...).
