And you need to have created and installed those profiles from elsewhere
before you can select them for printing or soft proofing. Those may be the
'canned 'profiles from the paper manufacturers or custom profiles.
Notice the perceived difference when a 'white' border is displayed in that
soft proof mode though.

Actually the new LR changes effectively duplicate Photoshop's printing
capabilities with more smarts added (resolution and colour space background
automation for two).
With most monitors in any case the luminance and contrast will not echo
well what the print displays (not even considering the transmissive vs.
reflective conditions). Few monitors can cover more than sRGB as well but
good inkjets can approach AdobeRGB.
A print on good Photorag might have a contrast ratio of maybe 150:1
compared to maybe 10000 :1 of a common LCD screen.

High end monitors like the best Eizos and NECs confer a lot of advantages,
including in these areas but maybe that is another conversation.

Cheers,
Geoff
