fedora

Steps to reproduce

1) In Nuke Studio, import an image.

2) Drag/drop the imported image on the Timeline to view it.

3) Open the Node Graph and drag/drop the image to create a Read node.

4) Select the image in the DAG and press 1 on the keyboard to view it.

5) Adjust both viewers for same settings (i.e viewerProcess: Aces(sRGB), channel: G, gain: 4, gamma: 3)

6) Compare the shot in both viewers, noting any discrepancies.

Expected behavior:

The pixels of the colorspace in the Timeline Viewer should match those of the Node Graph viewer.

Actual behavior:
There is a discrepancy when comparing the Nuke Viewer to that of the Timeline viewer when a colorspace is applied to the viewerProcess. Although the color values remain the same, it is visibly different per Viewer.

Workaround:

This issue does not occur when using the default non-OCIO Nuke LUTs such as: none, sRGB, rec709, etc.
