yeah everything looks way older and they explain it in the background lore as >they're just more powerful weapons and shields and shit
you can see the "in-universe historically accurate" innovations later in the additional movies or series like the mandalorian etc. for example the droids have of course been massively improved by the empire and there should be those dark super-droids everywhere during the time of episode 6.
Not even just the tech, but just everything in general is kinda shitty in episodes 4-6. Due to shitty acting/directing/production, the lightsaber fights are more talking than fighting, the stormtroopers act more like retarded droids instead of the highly trained well equipped SS soldiers they are meant to represent. and so on...
