The "sanitization" of Okinawan karate for public schools leading to Japanese Shotokan lasted for more than a snapshot - more like 70 years or more. It wasn't just Shotokan that lost many of the original moves by design - Okinawan styles did too, though maybe not as much, as their katas retained more of their original design containing the combat bunkai. Obviously you don't want school kids learning breaks and dislocates. Okinawans kept their kata unchanged pretty much, though did not teach the true applications to the Americans who brought karate back to the USA. So even though Okinawan katas had those moves, few American people knew it! No doubt, each dojo is unique in what and how it teaches. Every individual is different. But looking at the styles as a whole and the way the katas are performed, assuming the style is contained in the katas, a very noticeable difference can be seen between the two, as the video clips supplied by Mitlov show.
