For many recreational game players opposed to the small cadre of this games "Serious no Lifers".
You would be consigning them to a second class game citizen status of being able to almost see any GV through thier monitor maybe at 100yds in the brush. They would never understand the difference between the "Digital Vibrance", "Contrast", and "Gamma" sliders. Either in their LCD monitor's menu, video card menu, or even in the game's graphics menu.
Best Buy $199 LCD 21"specials just don't have the pixel resolution and vibrance to help you separate the iron from the brush without that icon. Even my LG L227 is an either or monitor. I can adjust it to have great grey scale gradient resolution and not burn my eyes reading on the internet or I can have great color and vibrance resolution and this game look great. But not both. And under $300 LCD's for general home/Internet use come set inbetween.
Thats quite a bit of unintended consiquence to not consider. Or, if you have a high end system and work at home as a graphics professional, I doubt it would do anything but make you more effective in the brush.
Would be intersting if the game had a wall in the sunlight where you can adjust your color resolution, crispness and gray scale for the game. I'm finding what looks sharp, bright and colorful on my desktop is a bit too gamma and contrast low in the game.
