Sure, which is my entire point - "Europe" isn't one place with unified rules everywhere. The "green arrow means you have unconditional priority" is actually a rule in Poland too.......except when it comes to this tiny side arrow for turning right on red. With that one you have to give priority to people crossing.

Same in Netherland. Arrow means it's guaranteed to be safe (unless a pedestrian is running a red light, which is possible and not an excuse to hit them), whereas a solid circle means you have to watch out for crossing bikes and pedestrians (though of course you should always watch out).
