Look for the exact laser amenity
A positive label is strong evidence that the venue uses one of IMAX's laser systems rather than its older xenon system.
high reliability verified
It does not distinguish IMAX's two laser configurations and does not prove that the screen is 1.43:1.
Use the film-specific format list
This identifies the venues and showings that IMAX says can present the film in that named format.
high reliability verified
Treat the list as film-specific.
Read the individual showtime
It identifies a 15-perforation 70mm IMAX film presentation for that showtime.
high reliability verified
Do not confuse IMAX 70mm with ordinary 5-perforation 70mm.
Treat a plain IMAX label as incomplete
The show uses the IMAX presentation system, but the label alone does not identify xenon, either laser configuration, film, screen dimensions, or 1.43:1 capability.

IMAX reports laser, xenon, and film systems in the network and says film may share a room with digital: https://investors.imax.com/static-files/acadcc0c-a764-4ad3-a59e-88d04bf2b140
Find published width and height
Published width and height give the most direct comparison of physical scale and reveal whether the screen is close to 1.43:1 or 1.90:1.
high reliability verified
Prefer the operator or building owner.
Use seat maps only as scale clues
The map can separate a small multiplex room from a very large auditorium and helps choose a centred seat, but it cannot reliably identify the projector or screen dimensions.
medium reliability reported
Use it as a scale clue, not proof.
Ask when the laser label is absent
A written venue answer can resolve an omitted listing, but absence of the laser phrase alone is not proof of xenon.
medium reliability reported
Listings can lag conversions.
Do not infer specifications from price
Price tells you what the exhibitor charges, not which IMAX configuration is installed.
low reliability verified
IMAX says exhibitors typically charge a premium, while its network contains several system types: https://investors.imax.com/static-files/acadcc0c-a764-4ad3-a59e-88d04bf2b140 .
Treat photos as a last resort
A photo may distinguish a tall 1.43-shaped screen from a wide 1.90-shaped screen, but perspective, masking, curtains, and cropping can mislead.
low reliability estimated
Treat the result as estimated and say why.
