I live in Japan, and have a US WiiU with a Japanese netflix account. I can watch the Japanese netflix with no issues, and if I use a vpn, I can also watch the US netflix using the same account. I'm guessing you'll have no problems either.
I'd suggest moving your netflix account to whatever...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
