Windows 7 x 64, Titan X (display+render) + 780ti (render)
Broken: 2.78.5 e0bc5b5 (2.79 test build)
Worked: 2.78c with git hub Filmic color management
Short description of error
When the color management Display device is set to sRGB, the view to filmic and the look to none (basic filmic log transfer curve without look shaper), the result is a filmic log transfer curve with the base contrast look active.
Exact steps for others to reproduce the error
Open Blender, use default scene, switch to Cycles render (or not), hit F12.
In color manager change view to Filmic, look at the render when you change look from none to base contrast, there is no change at all.
It means that the default Filmic view have a base contrast, it's not just the filmic log transfer curve.
Why it is important
It's important to have a defaut filmic view without look shaper, this way, when we save an image in 16bits tiff with filmic, we are still able to change back to linear space, by importing the image and set the image color space to filmic log in the N panel.
It means you could encode decent amount of data in a 16bits image, you couldn't do this with an image saved in sRGB EOTF view.
I noticed something too, the defaut view without any information on the transformation (sRGB EOTF) doesn't mean a lot. In the not so friendly color management topic it's better to have a minimum of informations to avoid confusion.
