Silly question, but do you set your white balance to something fixed before taking these shots? Most smartphones do auto-whitebalance, which would likely falsify the colors in many shots. Same goes for exposure settings, although these would only falsify brightness/contrast.
Also, just a tip for those who're lucky to own a smartphone new enough to do it: Use RAW images. They have a bigger dynamic range and can probably even capture the entire dynamic range of the projected film. Later you can load the raw image and recover full shadows and highlights. Many smaller cameras can do it too, like my Sony RX100 (but I'm not sure you would be allowed to use that one).
