For me, living in Poland, and using a VPN, Netflix registers on my Marantz as Atmos sound, but the picture is anything but 4K (let alone Atmos) quality. The only dependable high quality streaming is via Apple, great picture and sound. I think most providers, especially Netflix, are cheating on sound (reduced dynamics and detail, but all the channels are there) and vision, all of them. And we cannot quantitatively detect this cheat. My old BluRays, for example, the 'Lord of the Rings' trilogy offer sound, with dynamics and detail, beyond anything Netflix provides with 'Atmos'.
