Assuming You have the highest Netflix plan (that allows 4K) - there seems to be other limitations.
I am no Netflix expert - but for example this guide:

Suggests that to watch content in 4K you will need Microsoft Edge on Windows 10 - along with 'correct' Intel CPU and/or modern enough supported NVIDIA GPU.
