So the IMAX company renamed "Omnimax" to "IMAX dome" in about the year 2000, but some of the theatres kept the old name. Watching an analog flat screen IMAX movie on a dome seems like a horrible mess, but if you digitized it, pre-corrected the distortion and re-printed it to use not-all of the dome screen I guess it could work. Maybe you could achieve similar in the analogue domain with a special arrangement of lenses. I expect you could take an IMAX dome film, digitize it and translate it to the Sphere quite easily.
