Was checking out that explosion on the Japanese Special Collection LD and it also has more detail in there in the smoke and fire similar to the Technidisc on the last few frames. Still, I guess it's detail that is normally blown out when the shot is correctly balanced. But it's weird it's not there on your scans.
Anyway, your restored versions looks fantastic! So cool seeing all these familiar shots being brought to life. Like seeing them again for the first time.
