Toy Story, as far as I’m aware, never had a theatrical DTS track. However, assuming that this is referring to the DTS laserdisc (that was basically a DTS version of the original theatrical Dolby Stereo Digital track), there is a difference between the two tracks. Some dialogue delays that occur in this DCP exclusive audio track actually make it so that they are placed closely to the original theatrical track. The ending of the film before the credits start shows proof, as woody’s worried chuckle before it cuts to black is placed at the same spot as the original theatrical track, while on the comparing 2010 Blu-ray track, woody’s chuckle happens slightly earlier. I have a comparison of it somewhere in my video files, but it is a minor difference. I’m sure there are some other differences between the DCP track and the original DTS laserdisc/Dolby Stereo Digital track, but for now this should give an indication that the DCP track is different from the original track and the 2010 Blu-ray track.
