While you’re correct, Dolby Vision was done in partnership with Dolby, featured only in Dolby products, and isn’t a feature in products offered or supplied by Christie. Universal would have to go through Dolby to get them and that contract is done. The last Dolby installs I know of are Forbidden Journey Hollywood, Kong, and Fallon.
Contractually, it’s all Christie products on new installs/replacements. The new FJ Orlando projectors are Christie, F&F are Christie.
Here comes my backtracking though. Admittedly it’s been a couple of years since I’ve been in the parks. Have there been any new 3D attractions installed or updated since Fallon? I’m wondering what they’ll do once the Dolby projectors start wearing out. Will they strike a deal with Dolby to replace and continue using/upgrade to Dolby Vision, or switch to Christie’s 3D tech? What about older non-Dolby Vision projectors like Spidey, Shrek, and Transformers?
