As Hal pointed out, printing is irrelevant in this mode.  Behind the 
scenes, "Managed Display" should be doing a simple Image (or Working 
Space) Profile -> Monitor Prorfile transform, so that users with a 
profiled monitor will see the correct colours.

This mode uses a proofing transform, so that colours are shown on screen 
as they would appear if rendered on another device - usually a printer 
or press.  Whether this extra device profile is RGB or CMYK matters not 
one jot (not even at code level).

Why was this renamed to Press Simulation, BTW?  This mode is every bit 
as valid and useful for profiled desktop printers as it is for printing 
presses - hence it's potentially useful for digital photographers, not 
just pre-press operatives.

All the best,
