[Q] S Charger Cover White not really faux leather - US/European versions

I live in Europe, and just recently I upgraded from my old good Note 2 to Note 4 in white. I was disappointed about the cover, which instead feeling faux leather (like my wife's Note 3 does) is completely plastic and is extremely slippy.
I hoped that after upgrading to S Charger Cover, it may be more 'faux leather' but it is really not a case. The original Samsung's S Charger Cover is exactly the same plastic and slippy (in a way like Galaxy S5 cover is).
However I found out that US Samsung site lists White S Charger Cover under EP-CN910IWUSTA label while the one I purchased in Samsung Brand Store is labelled EP-CN910IWEGWW.
I wrote to US support, and they answered: "It seems EP-CN910IWEGWW to be a Non-US / International accessory. (...) Wireless Charging Qi Cover (EP-CN910IWUSTA) is made out of faux leather."

Now the actual questions:
- does any European user of white Note 4 has this feeling that both OEM cover and S Charger Cover are actually totally plastic and not a 'faux leather' at all?
- does any US user of white Note 4 can confirm if the white S Charge Cover EP-CN910IWUSTA feels like a leather not like ordinary polystyrene plastic?
