Yummy!
My mibox is still within returning window. Looks like I will keep it just for this feature alone. Apple TV 4K or shield can't do this.
Kodi HDR also switch correctly now.
Edit: official YouTube app is getting worse. No 4K or HDR, some video even loses 1080p
How can I monitor FPS? I've had no problems with 4k playback with either box even before Oreo but is there an app that shows current fps?
