There was a huge engine change in the late 1980s when the 767-300ER came out. The marketing teams didn’t make as big of a deal as Airbus/Boeing do nowadays, but that was a big engine upgrade and 50% range increase.
If you compare the CF6-80C2 to the original CF6-80A, the changes are similar to what the CFM56 to LeapX in scope. Similar with the JT9D to PW4000. 20% increase in thrust, larger fan diameter, higher pressure ratio, higher bypass ratio, etc.

Yes, for some reason they kept things quiet. If anything of the magnitude (PW JT9D vs PW4000) was done today, the type would probably get a new name and new house livery!
