Just flew back AMS-MXP, and I give a point about the discussion!
There were no check once landed in AMS from my flight from CDG... all was the same of the "pre-covid era";
AMS-MXP: at gate B0, the personnel has only checked my temperature and asked to fill a form were I declare that I have not any symptoms of Covid. Once fullfilled, they told me the "correct" gate of my flight.
Everything was very fast, clear and with no issue of any sort.
Thank you all folks!
