soft proofing

[frederic chaume]

Hi all

I'm trying to test different ICC profile relative to different paper 
support.
So in the image editor, I'm trying different soft proofing option using 
different ICC I have downloaded.
I'm setting Soft proofing to on , but didn't see any difference
I'm also using the Soft proofing view but I don't know when the soft 
proofing is activated and displayed and when not.
looking at the manual 
https://docs.digikam.org/en/color_management/printer_profiles.html , I 
notice that there is radio button in front of "Soft proofing view", but 
in my case I don't have it (using DK8.1.0 on windows). Is it normal?
Is there another  way to know whent the sof proofing view is activated 
or not ?

Thanks  and regards

Frederic
