Saved render looks different than Octane viewport

What am I doing wrong here?
The saved image looks a little dull; it has a tiny bit less contrast and colors doesn't look as vibrant as in the viewport.

I've disabled gamma correction in Max and save as 24 bit PNG.
My screen is calibrated with a Spyder Elite.

I save as 32bit tiff, gives exact same result or I disable post processing and save as half float exr, apply the color corrections in post.

Not sure if this is the same issue, but we used to get this with our old vray farm and now a couple of our octane machines are doing it. I have a suspicion one of us has accidentally ticked a gamma setting somewhere...

Sometimes our frames come out with the wrong gamma (blown out), even though we set it correctly in max. On other machines, it comes out perfect.

When we get blown out frames, the correct gamma compensation in Photoshop is .4545 (under the exposure/gamma tab) if you're rendering at 2.2 in max.

We render everything in open EXR.


Best,

tiff does this to me so we save as PNG
