I recently bought a 4K/HDR TV to replace my old regular HD flatscreen, and am surprised at how different the game looks in many ways, and quite a few of them are not for the better. I have seen some old posts about how the HDR was not implemented properly on console, but did not find anything to indicate that the problem was ever fixed.
The first thing I noticed was that textures were greatly improved, which was expected, but that the lighting is just horrible, especially for colored lights and even some brightly colored foliage. Everything is either supersaturated red or supersaturated ultraviolet blue. The overall brightness is very dark for everything else, so I have had to increase the brightness within the game to the maximum setting. The only other option under settings is a slider bar for the HD brightness, but moving it either left or right does not seem to have any effect. I have chosen the Game option on the TV for Picture Mode.
First of all, a comparison of one old snapshot that I was able to recreate:
Shadows in a lot of zones are a bright blue color, or change the color or plants drastically:
The stars are all bright blue instead of white
Auroras are flat and lifeless
Flora too bright
Lava loses its color variations
I used the Hectahame relic on my Thieves Trove to give it a blue/purple glow, here is what it should look like:
versus what I see
From what I can tell, objects that had red in them, plus some other color like yellow (fires, fire atronachs, etc.) have lost most or all of the yellow tones. Same for purple objects, they are now super bright blue. My understanding is that HDR should make the shadows darker and crisper but it should not actually change the color of things, especially if those things are light sources themselves. When I press Share to save a video I see a message that indicates colors in the video may look different because of HDR. I did actually go back and change the game settings to 1080p I think it was, but the bright colors remain.
Note that I only see these supersaturated colors in the game, when I watch movies or play other games I don't see this.
Does the game look like this on PC as well? Not to say that would mean that it is working properly, just curious.
