Yes, gradations are way smoother. I think sRGB EOTF is fucking with light to shadow transition.

Thx for the test James, I'm dubitative with this conclusion tho. A wider colorspace only allows for a slightly better GI (corona already benefit from that). The lighting part you mention in Vray is the consequence of the tone mapping curve embedded in the ACES view transform.
Lupaz is right, the scene needs to use the same lighting (free hdri or constant color) and the same assets (I see the widows suddenly disappeared in the Fstorm scene). For those who are wondering, the textures are from the corona library. Also, matching the initial exposure is important to start on a similar basis imho.
Good to know, ill have to have a play with these settings tomorrow. Cheers!
Seems like there could be a better way. Using the tag inside the VrayHDRI for sRGB or Linear. Anyway Ill stop derailing this thread with minor topics.
renderers.current.options_rgbColorSpace = 2
Yes you are correct Fluss. Textures are converted to aces cg space before rendering.
