I found this on Reddit about IMAX in DFW (3 years old):

Cinema tech here, I can answer with some authority on this.
So short answer is -- It depends on whats important to you.
If you're all about finding the largest IMAX screen in the area, the only game in town is Webb Chapel with their massive 6 story high screen, originally built for IMAX 70mm. But let me tell you why this choice is actually not the best anymore. The 70mm system at this location is the only on site system capable of filling the screen top to bottom and left to right. The location was switched to digital sometime around 2011, with twin 2K resolution xenon units. The 70mm system is now used only on occasion that Christopher Nolan demands prints of something be made. (So a total of 3 or so films since the conversion) So the height of the 6 story screen is almost never utilized, even expanded ratio scenes top out at 1.90, leaving much of the 1.44 screen blank.
The IMAX site I recommend right now is Northpark, which was just outfitted with the very rare IMAX with Laser system a few months ago. IMAX with Laser offers HDR, expanded color, and an 11.1 audio system with overhead speakers. The ratio during expanded scenes will fill the whole screen (although still 1.90 at this location).
But wait, allow me to suggest an alternative to IMAX -- Where IMAX with Laser is pretty rare, any of the dozen or so DFW area Dolby Cinemas at AMC offer essentially the same projection specs. Twin 4k Laser light Christie projectors are used to give you HDR with expanded color and contrast, and Dolby Atmos, which can address up to 64 independent speakers (using object based audio instead of discrete channels), besting IMAXs 11.1. They also use transducers built right into the chairs to add rumble to the bass. Dolby cinema won't use IMAXs expanded ratio though, so if that's more important to you than sound, you will want to keep that in mind when choosing your theatre. My favorite Dolby Cinema at AMC is village on the Parkway, which offers the second largest PLF screen in the area after Webb Chapel's.
