It's obviously clear that Linux still can only output what the drivers allow, but this has improved the output quality quite a lot.
I downloaded some 4k HDR Videos. First played them directly from USB drive on my Sony TV. HDR Icon is showing up. Now i know how the video is supposed to look.
installed Windows 10 with fall 2017 updates, let it update to latest version with windows update. After installing Intel Graphics Driver 15.60.2.4901 i can say:
HDR not working. HDR Icon in SonyTV not showing up, testvideo's colors look washed out and HDR switch in Windows Settings not is not available!
So make sure to update in the next some days and compare what you get from LE nightly (v18 based) in comparison to what your TV does on its own.
