Short description of error
[Please fill out a short description of the error here]
If you mark a JPG as Filmic Log, the image quality you see in the image editor is worse comparing with Compositor's straight output. This affect shader node's output as well.

Exact steps for others to reproduce the error
Based on the attached .blend file

Wake up the viewer node by doing something like turning "Use Alpha" off and on.
Compare the area around the neck to see the difference, the output by the compositor viewer node is the only one with correct quality
Turn on False Color, adjust exposure and compare the dynamic range, again, only the output by the compositor viewer node has the correct quality

Seems no longer the case in the latest 3.3, don't know which commit solves it, I am guessing these two?

Hope this can be backported to the LTS though.
