Consuming content anything else than the mainstream browsers on anything else than the mainstream operating systems or devices is definitely a power user feature, yes.
So where do you get more than 720p if you don't get it neither on open source operating systems nor on Chrome on Windows? If you get 720p max everywhere, why do you think this has anything to do with DRM?
Chrome on Windows uses its own Widevine DRM implementation instead of the OS-integrated one.
This shitshow is referred to as "robustness requirements" and Netflix apparently agreed to serve high-resolution video only to DRM implementations of certain "robustness" level (OS-integrated DRM with video drivers that co-conspire in enforcing restrictions on the actual device owner).
I can get the exact same episode or film — in any resolution — on my HTPC in five minutes, DRM free, by breaking the rules.

1080p is available on Explorer/Windows and Safari/OSX. 4K is available on Edge/Windows with HDCP 2.2 and "Intel's 7th generation Core CPU".
I don't know if this has much to do with DRM, or if it's just a matter of supporting HEVC.
Is watching Netflix at 1080p or more a power user feature? Because currently that's heavily restricted by DRM. Not possible on any open-source operating system, restricted to a few browsers on Mac and Windows. 4K is only enabled on Microsoft Edge and only if you also activate a bunch of hardware DRM features. So I have to watch 720p content on a 1440p screen which is ridiculous.
>But I don't see a lot of evidence that those limitations, if genuinely important to users, can't be competed away.
Amazon Prime imposes similar restrictions and is only slightly better at providing 1080p. Meanwhile piratebay still has more choice with more quality and is the only hope at "competition" to make them change their minds.
We are in a world where picking your devices freely is blocked by Amazon/Netflix and the content providers while at the same time those same companies want us to help them push for net neutrality. Commoditize the industries you depend on and capture the ones that depend on you seems to be the play and we should fight it wherever we can.
