Hello,
➢ Which platform are you describing? Windows I suppose.
yes, it is under Windows. If I swap the colour space on the monitor the
ICC-profile in the Windows colour management tab are changed accordingly. But
this does not help since PhotoShop looks up the profile only at start-up. So if
I change the monitor setting while PS is running the colours just get wrong.
So thinking about it (and EIZO support confirmed this) and if the colour
management is working correctly, as seems to be the case now, an image rendered
in sRGB will be display correctly on the monitor also if the monitor is set to
AdobeRGB.
As perceptual rendering is concerned, Graeme Gill pointed out in another
conversation, that this is not applicable if matrix profiles like sRGB or
AdobeRGB are involved. In this case colour management falls back to the
relative colorimetric intent.
Best wishes

Which platform are you describing? Windows I suppose. So how does Eizo promote
how it's auto-magical color profile config swapper is supposed to be used if
you have to know to restart your application to pick up the changes made by the
display driver? Or I am misunderstanding the scenario?
I swap display profiles under Photoshop on MacOS and it does the right thing on
the fly, so Eizo's thing seems sort of plausible. But also like a bug-a-boo of
compatibility issues.
As your report which kicked off this discussion, the concern of how a "larger"
gamut display will render an sRGB image differently than an "sRGB" display
still has some merit to me, for reasons that have to do with how to understand
completeness "sRGB" display response, and maybe (or maybe not) the nature and
use of perceptual rendering intent in display graphics subsystems.

Hello together,
the issue is solved!
PhotoShop checks only once at startup the monitor profile. So if I switch
the monitor setting while PS is running, it does not recognize this.
Now everything is fine and as expected. The colours remain the same (as far
as one can tell) if I restart PS after having changed the monitor profile.
The solution was pointed out to me by the EIZO support.
Many thanks for all your answers and have a nice weekend,
Hermann-Josef
