Indeed, from that comparison it looks pretty comparible.
However don't underestimate how much resolution can make a difference. Also youtube compression.
Playing games at 4K vs 1080p is a night and day difference in far off details, up close ones, aliasing, view distance etc.
It really has to be seen to be understood. I often swap between 1080p and 4K in my games, just to be wowed at how massive a difference in immersion and IQ it makes.
All that said, as a person who bought SLI 970's for this game and had to rebuild his rig over a catastrophic failure, all in hype for Wild Hunt. If I couldn't get the PC version, I would be very contented with my PS4 copy.
