I found the Stremio app in my Tizen app store today... immediately proceed to setup Torrentio + Real Debrid following the guide from Reddit (not sure if I can link it here since it involves jack sparrow activity). A quick google search will bring you the result anyway

Immediate impression, the app is straightforward to use and understand. But its not as smooth as the youtube or netflix app, there's some minor lag if you scroll fast and the animations are not as smooth. Still its usable and the most important thing is it works.... and it does well

To test my setup I went to search for a John Wick 4 stream with 4K HDR10+. Took few secs for the stream to start and after it does there was no buffering at all until the end of the movie (on Unifi 300mbps wifi). The image quality.... there's no QD OLED here but I'm still blown by it. And yes can confirm HDR10+ is working after checking the quick settings icon. Subtitles working fine as well

Was thinking to get a Chromecast for this but I think I'll save the money now. Also gonna cancel my Netflix subscription
