I think they are the standard tyres only from MY20 (maybe some MY19 as well?), as my MY18 lux came without the noise canceling foam. I was told the MY20 ones have less rolling resistance, so less CO2, but no mentioning of lower noise.
Have just checked my 22” tyres and they have the pcns (or whatever) letters and motif. I am surprised, as they still have high road noise compared to my D4 20”.
