We implemented various tonemap operators for the shader graph so they can be used for color correction or any other task that involves colors, textures and procedurals where they can be applied selectively to single image textures or a bunch of procedural nodes. They work great with HDR inputs like sunsky and environment maps and can be put inbetween them and Arnold skylight for example.
We have :

tonemap operators. Plus there's the option to first convert a linear input to sRGB and eventually back to linear once the tonemapper has been applied. Following is the original EXR image and then respectively ACES, Filmic, Reinhard, Lottes and Uchimura.
