nuke-default's sRGB and ACES 1.1 sRGB

Gonzalo Garramuño

I recently noticed a discrepancy in the sRGB output transform of nuke-default's and ACES' one. Basically, Nuke's seems to have an additional 2.2 gamma transform while ACES does not seem so pronounced. What's weird is that the ACES OCIO transform matches the equivalent CTL transform, but the nuke-default's output looks more like what is expected of the clips I am feeding (comparing them to a sample PNG taken from a web page from where I downloaded the clip from).

I tested the images both with my viewer and with the DJV viewer with same results.

Can somebody shed some light into the issue?

Find attached the two images of the "problem".
