Colour Management on two monitors - only one works

I have two different wide-gamut displays, both are colour calibrated with profiles correctly installed and assigned in Windows 11. I have set the the about:config colour management settings correctly in Firefox so that it should render with colour management.

One monitor display renders colours correctly, but the other displays the uncorrected wide gamut of the display. If I try a browser test, like Cameratico's, it confirms that the colour management tags are not being respected on the second display, but they are on the first.

Setting the force or native sRGB tags does nothing on the second monitor.

How can I fix this?

Thank you for the reply. No matter what settings I use (nVidia display setting, Windows display setting) the (lack of) colour management doesn't change. Other colour aware software, such as Photoshop, does noticeably apply the correct profile for each monitor when the window is moved from one screen to the next - it applies the profile as soon as you let go of the mouse button when you drag the window, so you can see it happening, and the images look the same on both screens.

I am looking to troubleshoot this. I'm sure others will have encountered this problem and be able to advise.
