In the Zapruder still you posted, I see a 4 inch disk of bone hanging down on the right, doubling the apparent size of the wound (the wound and the bone below it), and a lot of blood and tissue on Kennedy’s face.
In the first autopsy picture, it looks like the right side of his temple is gone. In the second, you see a disk of bone everted next to his right temple. The first picture shows what looks like brain all over his hair - it looks like there is a wound in the upper right posterior portion of his head but conceivably there could just be a mess of brains smeared on his hair. The lst picture shows an entrance wound on the lower part of his head, just left of center. His hair has been washed.
The pictures don’t seem inconsistant to me.
If there was an Establishment conpiracy to kill him, they could keep it simple - one deadly sniper, no need to fudge with autopsy pictures. Throw in Oswald as the fall guy if you want, but multiple shooters would be a foolish complication on the part of the conspirators.

The Clintoons learned the lesson?
Kennedy's wound and brain material were cleaned up by that time.
Conspiracists have been trying to establish Lifton's 'Best Evidence' theory using the difference between the Bethesda autopsy photographs and the medical illustrations for decades, just as you're doing now, but gave up quite a long time ago.
