There was acsccid manually installed from some time ago on that linux box which did not turn up in dpkg list, which made me assume it is the standard default CCID driver that is being used. Which made me wonder why it does not work on macos...

I noticed you were NOT using my CCID driver because it does not
support FEATURE_IFD_DISPLAY_PROPERTIES
But the ACS driver does return this value for readers with a screen.
