I haven't personally played through the entire game, however I know that
there is at least another FMV scene as you start, and I'd assume another FMV
scene at the end.
Here is a clip of the Sherlock Holmes FMV, this time side-by-side comparison
of the TurboDuo vs. Sega CD. The audio in the clip is from the TurboDuo
version with the Sega CD clip sync'd. Pretty big difference in color,
sharpness and framerate between them both.
