On the CE one, it will need to decode the stream in software, which it like PI it will struggle to do in 1080p. What you may need to do is go into your My Addons -> VideoPlayer InputStream -> InputStream Adaptive
and change the max resolution to 720, which it should be able to handle in software. I think it needs to be very good hardware to handle the software widevine in 1080. The Pi can't. But 720 looks surprisingly ok on Netflix.

Did the shield play a 4k stream via the plugin ok?

Fantastic, by adjusting the inputstream setting it now plays ok. Did have to tweak the audio delay. 

In Kodi netflix plays ok, I have 4k tv, left inputstream at max.

Thanks for this, I thought I was coming on helping someone, & end up being helped myself.

On my setup I've not had to adjust the audio for Netflix. my satellite was a little out on audio, so for that I had to bring it in a little. I think that's always a bit variable by hardware and source.

If you watch one of the Netflix shows that can be streamed in 4K does actaully show it's rendering it in 4k. Does it look 4K? It's not just upscaling a 1080p Netflix stream?

I think pressing 'o' (for Output) on kodi, shows an overlay on the screen showing info about the source. If I play an esp of season 6 of house of cards for example (which the plugin say is a 4k show) the overlay say 1280x720 which would be right on my PI as that is what i've set the max to. I'm just curious to know it's actually rendering full 4K from the plugin on the shield. Maybe it's totally obvious for you to see on the TV. I don't have a 4k tv yet, so I don't know.

And glad i could help! lol this forums often work both ways. Often found stuff I didn't even know that I didn't know here!

I can't tell by looking whether it's 4K. Kodi, mq8 skin shows audio as HEVC H265 HD2160 that is under OSD on screen display. I don't have O on my remote. Netflix Kobra Kai

Just found a keyboard,  O shows video stream 3840x2160 it looks like it plays 4K
