Drop down the RGB working space selector and in there
(towards the top) will be an entry 'Monitor RGB - profile name' - don't actually select this, but it's the
only place Photoshop actually confirms what profile it is using.
Note it only confirms the profile in use for the
primary monitor (the one the Photoshop menu bar is on).
Make sure you leave your correct desired working space selected as you exit this dialogue (for most people this should be AdobeRGB - much more on this here). This is just to check what monitor profile PS is actually using.
