If I am not mistaken, netflix HD@4K does not depend on Google Widevine L1 or Google cert.. like minix neo t5 it got proper google cert, widevine L1 but when I ask Minix on their official FB page, it is only capable of Netflix SD..
What I know of that Netflix 4K@HD requires Netflix ESN.. That is own Netflix certification.. that is why some devices like Gt Mini-A tried to spoof Xiaomi Mi Box ESN but later kantoi and will get error NW640-4..
Google certification ? We have to be specific. Google has various certifications. There is play store certification, there is ATV/chromecast certification, there is Google widevide certification.
Play store certification and ATV certification are all irrelevant as far as Netflix is concerned. But for Android platform, Google widevide L1 is relevant, because that's what Netflix depends on for end-to-end secure delivery of video content, to make sure nobody can make a copy of the content in between.
But Google widevide L1 itself is not enough. Netflix also require their own certification ( ESN cert ). So yeah, Minix gotten all the certification from Google ( some of them are irrelevant with respect to Netflix ) but they still short of ESN cert. Netflix refuse to certify their amlogic boxes.
On Android all these are relevent for Netflix :-
1. Google Widevine L1.
2. HDCP 2.2
3. Netflix certified ESN.
Short of one also won't work.
Netflix is not mendated to use Google Widevine L1 only. They can use other secure mechanism.
Kodi runs on various platforms, but they could only support Netflix upto FHD. But they can get upto 4k on Google platform provided that point 4 conditions are fulfilled, ie Netflix certification, Widevine Security Level L1 and HDCP 2.2 hardware.
