Short answer is...
No, not for the full frame for the full 1/3000s*. With electronic, it may be possible to come close, but even then there is not full synchrony across the frame.
This question is approachable via a mind exercise with the eventual conclusion that a shutter may approach full synchrony across the frame only as the frame size approaches
zero. Of course nobody would indulge in such a mind exercise unless they were
overthinking the realm of possible use cases. For the majority of use cases existing shutters represent a reasonable compromise where every point within the frame receives the same exposure, if not at exactly the same time.**
FWIW, freezing motion is sort of a happy side-effect of a faster shutter speed and is
never fully effective if you look close enough (i.e. have capture media and optics with high enough resolution). If the image of the object shifts more than one pixel during the exposure, it is technically not "frozen".

* Even with leaf shutters it is possible for an object to traverse the frame, yet not be captured by the film/sensor.
** After all, the aim is not to define the same range of time (point "a" to point "b") across the frame. Rather, it is to provide the same period (x # of seconds) for equivalent exposure.
