Yes, exactly -- I tried exporting to the display profile, and the images look exactly the same -- basically correct, but oversaturated.
And there is only one monitor on this system.
I just tried exporting them with Generic RGB profile -- same results -- identical somewhat oversaturated colors.
It seems like if the Photos screensaver was truly ignoring the profiles these versions would all look different from each other, wouldn't they? Given that they all look the same, it seems like the screen saver is interpreting the profile, but then boosting the saturation for some reason. But it does not explain why I am only seeing this on the wide gamut monitor.
So I am stumped.

One would assume that if the screensaver application is simply throwing up(!) raw/untagged RGB values to the display that exporting or converting to the display profile would render the images correctly, regardless whether the image is tagged or not.

I would suggest to the OP to verify the profile that's being used on the primary display and see if converting to THAT profile renders the image correctly.
