When adjusting Convert to profile options in RGB document, the preview does not actually show the color change when the rendering intent is changed. They become available only after applying the profile.
The Proof colors preview also does not show the actual color changes - you can endlessly switch settings in the window and there will be no changes to the image. To see the simulation of the profile, you need to enable / disable Proof colors.
Tested on two different computers (win 10, win 11, both with the latest updates and updated drivers). I reset the Photoshop settings - it did not help.
