Fortunately, modern TVs can disable the sharpening and contrast/saturation enhancements. Since I do a lot of photography and image processing, I am also extremely sensitive to oversharpened halos, so I was a bit worried about that at first --- but fortunately, that is 100% nonexistent once I applied the appropriate settings on my Samsung QN800A. See pics: [1] [2]

I also detest the miniled HDR that they have going on, which can cause bright things to glow, so I disabled that. Unfortunately my QN800A still have a bit of "full screen HDR", namely, that the whole screen may uniformly dim if it detects that the scene is dark. This means that sometimes when you have a black screen with a single cursor on it, it gets dark, and it becomes hard to see the cursor. This doesn't affect normal usage though, when the screen is at a constant brightness.
