Haha, travel more buddy, the dominant culture is the country's own culture, not the one from the US.
You know, the US adapted Beer and Sushi too.
BTW: Movies, Games and "Social-media" is NOT Culture but cheap entertainment.
Here, If you are aware of new wokeness trends in the US is question of about 3 months until the spanish left and media start parroting the new word, idea or whatever.
The consumed culture is overwhelmingly US based. Netflix, social media... The local shows that happen to succeed, mostly are created due to legal obligations imposed by the goverment. If it were not for that...
Oh and the leading newspapers basically parrot a lot of what they themselves read in New York Times, incl. doing interviews with American book writers or even discussing American racial issues (hard to find an international issue less relevant than that to people on the ground in Poland) etc. That's also partly because most of them don't know say German, French or Italian, so they can't really be influenced by those cultures quite as strongly.
