Not necessarily - or, at least, only from a small minority who is in charge of the processes at some point. In my experience, most Germans today, especially the younger generations, "just do their job" and really only are motivated to do stuff in their free time. (Not unlike most people elsewhere.)

Symbolic for the receding importance of precision in particular, in my observation, are for-the-wide-public and even half-professional technical writings (and TV reports/documentaries) - numbers are rounded, details left off, even confused or plain wrong, sources used without care. Just in my field, ironically, it's now the Spanish press releases that give say the length of a tunnel to be built down to the tenth of a metre and the costs to the last Euro-cent (literally!), while the German ones will round to the nearest first or second digit. The releases of the German Statistical Office are a much wider-reaching example.

I have observed at first hand

May I ask where you have been on a German university? What you describe sounds rather different from my own experiences, it could be because you have been to a conservative school and I haven't. (Come to think of it, I barely knew CDU supporters.) Alternatively, this could be a rebel-against-parents-but-adore-grandparents thing of the youth half a generation after me...
