Not really, reliably detecting a user's preferred languages has been a persistent Hard Problem in tech since the start of the internet. Every proposed alternative solution ends up having vastly more false positives due to browsers/people incorrectly setting of default preferences so companies begrudgingly default to geographic heuristics knowing it is a terrible experience for an outlier group of people.
Yet this implementation that Youtube uses is in the bottom 1% of worst ones. Strange how roughly every other website/app does a better job at it.
Why wouldn’t you just ask them, and particularly for media like this that has a native language, default to that? I don’t want software to think for me about what I want to see, if I want something different I’ll change it.
