thanks, I quickly read the posts (and somehow remember his blog / forum).
As you like printing on matte paper, you are ‘elected’ for colour range conversion. 
If I’m not completely wrong …
You have a file with out of gamut colours (but how to do that, when PL4 is your raw-converter und PL’s workspace is AdobeRGB ) and put them to paper, just with an ICC-Profil, I don’t think there is any rendering intent ‘magically’ applied. With that, you would get oversaturated colours, which are responsible for loss of textures (if there are).
IF that is correct, you better choose a rendering intent, that should be either perceptual or relative colorimetric. – RI absolute is not ment for ‘normal’ use.
I think it’s saturation, that’s used e.g. with advertisments containing ‘spot color’ (don’t know if it’s the correct term), that is a distinct colour being an essential part of the company’s logo / design >> corporate identity etc. RI saturation cares for the correct transmission of that special colour (of course not out of gamut, otherwise not printable), but neglects other colours, as they are not that important. – And RI absolute is used for softproof between different media (something else like that).
With that, ‘we’ normally use RI perdeptual or relative colorimetric, depending on how we want out of gamut colours to be handled.
I just checked PL4. In the printing process – still do my printing with PS – you can choose a profile plus a rendering intent like in PS, but no softproof around.
Now, I re-checked the blog and he says, he usually prints with RI relative colorimetric, and only when he is not satisfied, he tries again with RI perceptual. – I assume, it all comes down to one’s workflow. etc etc
That’s it for now – w’ll keep in touch.
have fun, Wolfgang

macOS has a ColorSync utility that, if you open a file with it, shows you a soft proof of whichever profile you select for a given rendering intent.

@mujabad So it’s this, she was referring to. – As I don’t know about MacOS, can you desature (or whatever) in QImage AND see the softproof in your OS at the same time?
