Why are 'Looks' appearing different in the creative preview than program monitor?

[JoshForwood]

When browsing looks in the Creative tab of the Lumetri Color window, the preview can look drastically different to what it looks like in the program monitor when I apply it.

This is without making any other Lumetri adjustments on any of the tabs. The preview is definitely working as I can see it change as I flick through the different looks, and the colours that come out in the program monitor (as you can see in the 2nd example below) definitely don't look right.

If you have any ideas or suggestions they'd be greatly appreciated!

Here's a couple of examples (Preview window on the right, program monitor on the left):

Does this same problem occur if you use the included looks that are provided in Lumetri versus third party?

I'm not seeing this issue, but am not using any looks other than the Adobe provided and/or camera manufacturer suppied ones.

To be honest no, it only seems to happen with 3rd party ones, but not all of them. But I don't understand how this could happen, if the preview is reading the look properly, how is it getting messed up when being applied? 

[Meg The Dog]

Don't know, but likely the 3rd party looks are not compliant in some way - or they rely on adjustments that force the image components out of range of the format you are working with on the timeline. Just a guess -don't use luts that often.

Hang around, maybe someone will offer a solution.

Thanks. I can work around it but would be interested to see if anyone has any possible solutions to offer.

I found that the preview screen only shows how the LUT will look on the raw footage. If you have added other corrections like contrast or curves, it will not be added to the LUT preview, so by switching these off the preview should look exactly like the program monitor.

For a user, I've got about as much experience/knowledge-of the Lumetri process as anyone. Yea, I've seen that occasionally you can get differences between the "preview" monitor and the Program monitor. I accept the accuracy of the program monitor. The preview monitor ... I'm not sure how tightly that is set in truth.

But then, I've never expected the preview monitor to be an end result.

Out of curiosity, if you go to the Creative tab's settings for Intensity of the look and back it down some, does it then look like in the preview window?

If you change your Premiere color managements setting in the Preference/General section (enable display color management) ... does that affect this?

Oddly even if I reduce intensity to 0 it still comes out drastically different (see below).
I've also, on your recommendation turned on display color management, but to no avail. 
Thanks for your help but let me know if you have any other suggestions

Did you end up resolving this issue? I am having the same problem!

Yep still same issue here...
