Nokia is evidently adding some more customization options for Nokia Lumia 920 users (and possibly their other WP8 Lumias). The evidence comes from the latest update of Nokia’s display + touch app, which allows users to control the SuperSensitive Touch and sunlight readability options.
Now there is a third option called “Lumia color profile”, which will allow you to make your Lumia 920 “Vivid” or “Natural” by using a slider. Likewise you can change the color temperature from “Cool” to “Warm” on a second slider.
This will be the first time on Windows Phone that users were given access to changing more than just brightness on their display and it shows how Nokia is continually offering improved experiences.
