The Dragon Book does note a few reasons for certain scenes being re-animated, such as the removal of “extreme changes in brightness” and in general just “replacing cuts that have degraded over the years with refreshed images”. To elaborate a little more, here are a few reasons why we’ve seen certain scenes re-animated in the series:
Update ki attacks with modern effects.
Remove bright flashing and strobe effects.
Correct animation errors and inconsistencies from the original series.
Extend certain fullscreen scenes horizontally to ensure key elements properly fit within the cropped widescreen framing.
Edit scenes that are deemed to contain unsuitable or obscene footage.
