I may be an idiot, but: What does this actually, y'know, achieve? It seems the answer to me is probably nothing?

It doesn't work on Firefox. It appears not to work on Chrome. The suggestion is to use Edge, which on Windows already gets 4K support in Netflix anyway.

Fellow idiot here, and the gist seems to be:

Here's a 4K enabler that only enables 4K where it's already enabled.

You misread the README. Although it suggests using Edge at the very bottom, the extension doesn't require it and actually spoofs Netflix into thinking it is Edge via changing the user-agent.

Did I, though?

I understand it spoofs all of the checks it can, but the only Chromium browser that supports Widevine L1 (a requirement for 4K) is Edge, so even if all of the check spoofing works, it still won't do 4K.

There's even a table in the README that describes this exact scenario.

I believe the benefit for Edge is faking HDCP 2.2.

Then why does the extension try to fake a bunch of other properties, like the user agent and decoding capabilities, which should be redundant?

[doctorpangloss]

i don't think it works! there's no mystery here...

I can't vouch for this extension in particular (because I haven't tested it), but I've used and written similar extensions myself and can confirm that the concept is legit.
