Hi Lou. I can confirm what Refik is saying from having made on-screen measurements• using an i1pro and Spectrashop a few years back. Regards Peter Miles *A few years back I wanted to clarify in my mind the same question Lou asked. So I measured the on-screen colour of a soft proof in photoshop when the 'simulate paper color’ was on. I compared that to measurements I made of the display white point. I did this on a profiled Eizo at a 3 different white point settings . From the measurements it was clear that the on-screen colour of the soft-proof (with ‘Simulate Paper Color’ on) was different for each display white point used. And from comparing the ab plots in Spectrashop it was also clear that the on-screen colour of the soft-proof (with ‘Simulate Paper Color' on) was being shifted ‘relative' to the white point of the display.

No, they will not look the same, The paper white simulation is "relative to your monitor white point".
