It is unfortunate if you truly believe this. While it is true, in my mind, that we don't need every release every manufacturer puts out, many of them are different enough for different types of bowlers to be considered as useful tools. That is one of the keys to buying a "ball reaction": is it useful for you? (I'd rather not get into the details of a THS vs sport oil patterns at this time.)
There are two factors involved in that video that blur the line between the different balls. (For whatever it's worth, I also did not find this video of use to me at all either.)
One is the type of bowler portrayed. People who throw a small hook will naturally show much less difference between balls than a person who throws a larger hook. It does not have to be some super-cranker with 500 rpms, but an average tweener of 300 - 375 rpms might better show the differences between balls.
Two is the lane condition that allows misses left or right to hit the pocket. To my mind, such demonstrations would be better served by using flatter oil patterns IF ONLY TO SHOW what happens when the bowler does miss his target. Manufacturers would, of course, prefer such demos to show only strikes, but we, as bowlers, would learn little about the ball.
