The Video Playback, while at a lower resolution It Does depict the difference between
HDR OFF, and HDR ON.
It is a significant difference.
True, You can't capture true HDR 10, at 1080p and even if you could, you couldn't view it unless you had
a HDR 10 capable system.. Not Sure if Youtube even supports HDR 10 encoding.
The Point of the Video is to show the big Difference between
HDR OFF, and HDR ON.
I drove the Laps, Once with HDR OFF, and Once With HDR ON, I saw first hand the Big Difference it makes.
I recorded the Video's using the Share Button.
and I watched the replay of the Videos.
It is a pretty Accurate representation of the Difference.
I think, Because I created the content, I can verify it's depiction of that content.
i got a message on my ps4 pro saying something like "video can't capture hdr correctly" when trying to record some Horizon footage.
when i then watched that hdr video the colours looked much to saturated! so i think you cant capture hdr content on ps4 yet.
Was Horizon Produced with HDR 10 encoding in the game?
From what I read It wasn't. It supports a 4K resolution mode, but doesn't use the HDR 10 color range.
GT Sport was. GT Sport takes full advantage of HDR 10 color spectrum.
So If Horizon wasn't encoded for it, then I'm sure you are not seeing HDR 10 from it.
