Apple is 45% of the US smartphone market, and something like 20% of Europe's. So Apple's sales will not be the best indicator of anything generalizable to all smartphones.
Apple is 33% of Europe's smartphone market, almost the exact same size as Samsung, the #1 player.
Knowing that almost all of Apple's phones are >$800, the fact that 41% of all sales in the EU were >$800 implies that Android isn't some hidden variable here.
I'd also like to point out that unit shipments have been in decline (on a y/y basis) for 10 the last 13 quarters. [0]
Europe is around 45% smaller than US revenue for Apple (and about 25% of overall revenue) and has lost share every year since at least 2018. [0]
The US and Europe see similar volume sales (both way less than Asia).[1]
It's just simply not true that Europe is by any means the largest smartphone market at any segment.
