Base Color on Buffer Visualization Overview isn't gamma corrected

https://udn.unrealengine.com/questions/391311/buffer-visualization.html

Open the minimal default level in starter content.

Turn on Buffer Visualization, note the color of Base Color

Switch to Base Color only, instead of "Brady Bunch Mode"

The result is gamma corrected

(You can verify this by sampling the colors and using the color picker, if you're curious)
