I'm no delta E worshipper but I sometimes cringe at blanket dE
numbers such as "< 2 dE not distinguishable". I can tell you for a
fact that .75-1.0 dE on a midtone gray patch is certainly visible
while 2-3 dE on primaries/secondaries is difficult to see. In other
words, it depends.
As far as all RIPs getting decent dE numbers and an excellent visual
match, 'tis true, but the distinguishing feature among the higher-end
RIPs is the ability to MAINTAIN that level of accuracy. There's only
a couple of RIPs that I consider to have the right technology to
maintain those kind of dE numbers over time (needing to re-profile
the entire system doesn't count in my book).
Just my .5 dE worth. :-)

those very slight differences are dwarfed by the variability within
a press run, let alone multiple runs . At this point (IPA proofing
Roundup results show) all the major proofing RIPs (EFI, GMG, ORIS,
etc.) are giving outstanding results (even better than we need)
with the main differences relating to ease of use and cost
(including, by the way, consumables, with certain companies locking
customers into extremely costly proofing paper--not a trivial
consideration for many customers).
