Wire,
Is this what you're looking for?

Opinion about balance between AdobeRGB and Display P3 in consumer gear?
Honestly, I don't know. I don't know at what rate are wide-gamut monitor
prices coming down? I'm not sure many "consumers" care all that much or are
the least bit knowledgeable about the gamut of their displays? As far as
Apple's products are concerned, it may give their engineers "good
conscience" to know they are adopting a "new" standard for display, P3, but
I suspect most buyers are not all that preoccupied and certainly wouldn't be
swayed to buy an Apple product because of their "adoption" of P3. I read
elsewhere that Microsoft's Surface Hub has P3 as its "native" space?
As an experiment, I tried to set my PA271W in its native gamut, if only to
measure the primaries, but I quickly reverted to sRGB emulation because the
colors were too vivid?
You mentioned NTSC and I was surprised to see how far it reaches into the
greens, not so much into the blues but almost on the nose of the spectrum
locus for the red primary. Quite a feat. Could it be that televisions were
made with these primaries all the way back in the '60s, '70s, '80s, '90s?

Roger thanks (and Andrew) for looking that up and plotting.
Would you replace previous NEC model plot with NTSC 1953 and post your graph
over on the DisplayCal thread you recently commented... The graph clearly
makes Vincent at DisplayCal's point about combined P3 / Adobe coverage
possible with some new tech. And I think it will show that consumer displays
(higher end) have finally arrived at the color spec laid down when ENIAC was
the next big thing (figuratively haha)
What are you opinions about the balance between Adobe RGB and Display P3
coverage in consumer gear? And challenges of wide-gamuts in general. I'm
interested in your opinions as both what you think personally and your sense
of industry trends.
