Um, I'm pretty sure you can't store a terabyte of information on an optical disk. Even if you split it across multiple disks, like Laserdisc did, there's no way to get close to an uncompressed 35mm 4K scan (at the least). I'll admit, off the top of my head I don't have exact figures, but the space to save a 35mm scan is at the very least in the hundreds of GB range, and I'm pretty sure, actually in the terabyte range. Aside from which, digital display can't 100% replicate the color and density of film.
