As a Photoshop user, I'd agree with both points (although anytime I hear the
term "accuractly" the hairs on the back of my neck raise).

This might be useful for geeks, I'm not sure it would be useful for other
users. I don't find anything really useful in the gamut overlay. The soft
proof is far more useful although it needs a bit of work and our displays do
have some important limitations too. If I can't print it, I can't print it.
I would like to see the effect, the overlay doesn't do anything beneficial
in that respect.

The customize soft proof. Note, I am working with both conventional "sRGB"
and wide gamut displays (neither is close to prefect). But I want to see the
customize soft proof with the paper and ink simulation ON next to the same
image without (currently that means I have to duplicate the document which
should be addressed) and having the rest of the PS UI without white
simulation on isn't helpful. But I attempt to do minor editing to the
duplicate image to pull it closer to the original. That usually means a few
slight tweaks to curves, and Hue/Sat on adjustment layers in layer sets
named for the profile and intent I'm working with. There's a lot that could
be done in the customize soft proof to make this all easier. I think it
would be even more ideal in the Lightroom environment for a number of
reasons I'll refrain from discussing here.
Bottom line is, I want to SEE a good simulation of the printed piece on
screen (tough to do), not some overlay that tells me those colors are out of
gamut.
