I haven’t gone back and tried my old 8k to compare, without that nothing stood out to me about the colors.
My PC is a fairly powerful gaming PC, though not top of the line. 1080ti, 16GB RAM, Ryzen 5 1600X. I had to lower settings in Hellblade for it to run at a good framerate.

Everyone posts pictures of simulators or Skyrim. So here’s some more variety 
Vader Immortal
Hellblade: Senua’s Sacrifice
Virtual Desktop (note: my screen resolution is 4k)
And just for fun: Somnium Space, a virtual world I own some land in
