Sure but none of those improvements had any sort of “wow” factor for the target audience - who were primarily interested in graphics, sound and CPU speed - particularly wrt to gaming. ECS is a marginal improvement, otherwise you’re still looking at 7 year old technology. What killed the Amiga as a mass market device in Europe IMHO were the new consoles - Megadrive and the like which blew it out of the water in terms of eye candy and speed.
But MegaDrive games don't look inherently better than OCS Amiga ones - and sound worse to boot. Compare Desert Strike or Battle Squadron which had a version for both systems. Maybe SNES was an improvement; the main advantage was the price of the system instead (and the hidden cost was that the games were 2x - 3x as expensive, which added up quickly).
