The SE ending of ROTJ provides a massive change. We see celebrations on various planets; including Coruscant, during which we are led to believe that the Empire has fallen.

It implies it, but it's not for sure. Riots can last for a night, but that doesn't mean the government's done.

In the GOUT, we merely see a small celebration on the moon of Endor. There is no reason to believe the Empire has been completely overthrown. For all we know, someone could have simply stepped into Palpatine's shoes and taken control of the remaining fleet.

The tone of the end of ROTJGOUT makes the same implication as the ROTJSE, even without the riotous imagery.
