What is the Image P3 color space in Photoshop meant for?

[Taipalus]

Does it have anything to do with DCI-P3, or Display P3?

Mysterious that ImageP3 - its not installed on my Mac despite many installed Adobe apps 

Conrad C's post & linked article above gives a fair bit of info.

It would help to know specifically why you are asking?

I hope this helps

Giving conrad C's post and article another read I understand the difference better, was trying to "see it" in calibrating a middle of the road monitor (trying to make due with it for the moment and it has both profiles listed) to use with the new MBP 16". For some light Illustrator work and getting back into Photoshop (non professionally).

Is that the M1 MBP? With major changes to the System preferences / displays / color dialog?

Yes, the M1 MBP 16". The display out of the box is phenomenal and I use the iPad Pro as a second (small) monitor also. 

I just needed some additional affroadable screen realestate (for doc references and light ai dieline work) until a prosumer/consumer XDR display is available. I understand an LG QHD Ultrawide is no where near a 4K option and the Pro XDR display but trying to dial the color/clarity in as best as possible. 

Thanks for this link re the MBP calibration, very interesting.

Display P3 and image P3 have the same color gamut volume.

The Display P3 was created by Apple and was intended to be based on the display.

In other words, it is used for mobile phones and other high-resolution displays.

So Whitepoint is 6508.6K.

The rendering intent compresses the color based on the perceptual.

I created image P3 for print-based use in Adobe on Display P3.
It has the same color area as Display P3.
Since it is built on a print basis, the white point is 5002.9K.

The rendering intent compresses out-of-area colors in a relative coloratrix manner.

@jonadan kim if you are describing an issue you have, please explain what that issue is? 

You mention rendering intents both perceptual and Relative Colorimentric, is that part of your issue? 

I hope this helps

It seems I was wrong - I have assumed Display P3 and Image P3 were identical, but they do have different white points. Not that that matters in practice. No standard color space supports anything other than Relative Colorimetric, which always  remaps the white point.

So does Perceptual, which apparently Display P3 uses. I'm a bit curious about that. Theoretically, it should reduce the visual effect of clipping on screen when displaying ProPhoto data. On the other hand, it also affects areas inside the gamut limit somewhat. So you could say it prioritizes pleasing display over absolute accuracy, but that's a tradeoff I suppose we can live with.
