[Tig] 3D screens

So to make up for a lack of brightness 'cause theaters are too cheap to have
good projectors, they're supposed to put in special screens to make up for
this lack of brightness??
I am not impressed with 3D watching thru glasses that obstruct my peripheral
vision and definitely seem to change the image quality negatively despite
the efforts upstream. The real 3D glasses really seem to impact contrast
ratio and maximum highlights.
Why do we have to wear sunglasses at the movies!?!? This is now better?!?!

Screen manufacturer Harkness says (in comparison linked below) "When
3D auditoria are showing 2D content the screen will generally be too
bright, so lamp power should be reduced."
Is it possible that something got changed between the time the DP took
the spectrometer to the cinema?
When the DP measured, were polarizing filters for 3D pulled out of
the optical path? Or somehow reinserted before the screening? Lamp
brightness adjusted? LUT changed?
Was the auditorium he measured the same auditorium the premiere
actually took place in? (Maybe a last minute change by the cinema to
accommodate more/less people?
Were you sitting in the center of the auditorium... or off to the
side? If off to the side, how far in degrees?
There are so many screen types, for different situations:
Harkness has some useful information comparing 2D and 3D:
There are further links at the bottom.
No connection to any of the screen manufacturers... just curious about
the differences in screen types and how they might have affected your
How does the show look in other theaters that may NOT have 3D screens?
