There have been numerous Samsung phones, and phones from other manufacturers over the years that had higher storage internationally than in the US.
I used to work for Verizon, over 75% of people bought the base storage iPhone, the highest storage was so rare we didn't keep them in stock at my location.
Galaxy S6 had storage options, same thing, almost no one paid for higher storage. It resulted in phones sitting on the shelf for over a year and getting clearances out at a loss.
Don't ask me why, but few people pay for more storage.
International Note 8 won't work on Verizon by the way, they don't have the CDMA radios on the Exynos phones. They need to pay Qualcomm to include them, it's why they use Snapdragon in the U.S.
