On one hand these pics do not do justice to in person look. On the other
hand, it's amazing I expect a phone cam to give anyone a fair sense of
what's going on... and it does! We truly live in a marvelous age.
Part of what you are commenting on in pics is normal IPS off axis response,
related to "glow". The phone's adaptation really amplifies the effect.
Sitting in front you would say it's not significant. If you tried to call
it out, you would notice that other off-axis effects are more discernible
as you just shift position in front of screen... And IPS is known for
quality viewing angles! They key is side by side, your attention will not
be called to the difference, you will notice other effects.

I mean that in Adobe RBB mode, it's not unreasonable to predict that Dell
hits 2 delta-E conformance across the population. IOW, yes consistency
across the face of one panel, and conformance of the population to the
standard color space.

Ok, thanks for the encouragement!
Thinking about getting this all scoped out and into a blog to post for DCal
forums too.
