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.
