not knowing my skill/knowledge level with PS

Exactly, thanks for not taking offense, better to start from the ground up and not make assumptions. So, you open an image in Photoshop and in Preview, on the same monitor, and they look different.

In Photoshop if you are leaving the image in it's original space when opening, then Photoshop should be doing a match from that image's embedded profile to the profile of the display with the menu bar. Preview will do a match from the image's embedded profile to the profile of the default display set in ColorSync Utility. So for these to be equivalent, you'll have to make sure the menubar display is the default display in ColorSync Utility.

Sometimes calibration apps don't set the display profiles correctly, to avoid that you can use System Prefs - Displays - Color to make sure the profile you just created is really assigned to the right display by selecting it in the list of profiles. By selecting different profiles you'll see the screen change color somewhat if the profile contains a VCGT tag, which it should.

It sounds to me like the problem is related to having multiple monitors and the difference between which display profile Photoshop uses to match to, and which display profile Preview uses to match to.

One problem you might run into is that you create a profile, it's assigned to a monitor, but after you reboot it's not. This happens if there's something about the profile that the display manager doesn't like, something nonstandard, and when you reboot or log in the display manager rejects the new profile and reverts to something else. That might not affect your case if the Photoshop and Preview relevant displays are the same, but it's worth keeping in mind.

Another problem that can happen is when a calibration app creates a profile but assigns it to your other display, that's why it's best to check with System Prefs. _______________________________________________ Do not post admin requests to the list.
