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.
