I just tried the Smart Youtube TV app and tested it with the Morocco in 8K video. I noticed that even though it's playing at 4K 60 fps VP9 on the best bitrate possible, the image is a bit softer than in the official app. There are also signs of tearing and weird artefacts in some edges. They are barely visible, but I definitely noticed the difference in sharpness. I did A/B testing with the same scene switching back and forth quickly. Has anyone else noticed the same? I have a Nvidia Shield Pro 2019 btw.
I didn't notice any difference
