FWIW I noticed some time ago that AH can look very different depending on the monitor. On some it looked dull and flat, on others it looked vivid and interesting. Further investigation revealed that the monitor presets can do a lot! Instead of using the neutral setting which looks nice and calm when reading the forums and performing home office tasks, try something like "game", "movie", "photo" etc. They may make the forum look glaring or even blatant, but one of those can make the game look supernaturally vibrant. As it's only beyond a few pushes on the buttons of your monitor it's worth trying!
