Ho to understand on what color space my LUT has been designed?

Hi there,
I have got from a LAB a LUT .3dl 16x Mesh point which is supposed to be used for generating dailies. I'm wondering to know if this LUT has been made for a 709 or a P3 gamut. Is there any way to understand it though LightIllusion? (I don't trust the person said that it's 709).

If it's P3, can I add a P3 to 709 conversion at the end of my grading node (LOG- GRADING - P3 LUT - P3 to 709) and make it work for my dailies 709 environment ?

Best,
Luigi

The simplest approach is to use a display of known colour space - say Rec709 - and then look at a known image through the LUT.
The image needs to be from a source the LUT was made to work with - images from the camera used on the production.

You will quickly be able to tell if the images look correct or not.
If for a P3 display the images on the Rec709 display will look over saturated.
You can then use LightSpace CMS to concatenate the LUT you have with a P3 to Rec709 LUT to correct the LUT.
