Anyone know the screen ratios for the IMAX theaters in and around Houston?

Thanks to Oppenheimer, I fell into a bit of a rabbit hole regarding IMAX formats and now I'm trying to figure out which kind Houston has. If i'm going to watch Oppenheimer in IMAX, I'd rather it be as close to the original film ratio as possible because there's no 70mm IMAX theaters in Houston. I really can't seem to find any information online on which IMAX theaters have which formats.

Additionally, anyone know when Marq*e's IMAX will open back up?
