> With Netflix, there are never visible artifacts

Uwotm8. Any sufficiently dark scene will have artifacts out the wazoo.

Not to mention other stuff like subtitles mentioning the wrong spoken language (ie. the character is speaking French, but the subtitle say they're speaking English), the UI unloads after some time, and the only action you can take is to start the video (you can't go back), the button for info when hovering over a card doesn't work half time time, video controls disappear at the end of an episode while transitioning to the next (the 'next episode' button is present and animating, but you can't pause the video at the credits in that moment), etc... In short, the UI is shit and so is the video quality.
