Why is it important what was possible or impossible back then.
The fact is that EoE couldn't hope to achieve that, or scenes like that would've been implemented with the same kind of quality.
They weren't - and it would look completely different as well to the point where a comparison would then again be completely moot.
You are somehow confusing what's technically possible with what is affordable to make and animate.
That's why you see the heat emitted from the engines of the military flying machines-things in a close up in Rebuild while in EoE they look like they work on invisible magnetism and the engine is basically suggested by not colouring that part at all.

If a show can't afford it, it's not in there, if technology makes it affordable, it's in there.
Thus the quality of the product increased, through technology.
The earlier example you used about how artists were able to paint the reflection of a room on a vase or whatever is pretty irrelevant.
Animation is an industry, you get X hours per project. Back in 1995 as well as in 2024.
Digital Art made it possible to complete stuff faster, with better/same quality due to how the tools assist the artist.
And it's not only that, you ignore the fact that stuff like resolution is a thing and thus all kinds of details that previously perhaps have been actually drawn (or could have been) are lost on the device it copied onto.
Shinta is 100% correct, factually, because that's just a thing and something that's still true today in many cases, most notably in computer games for example.
But even in movies, and in anime as well.
On top of that, you can actually zoom in on digital art and get pixel perfect detail, you can't do that when actually drawing with a pencil and if it has to be coloured, it gets even more messy.
It's
physically impossible to achieve the same detail digital art allows you to, even if you go out of your way and say that artist work like people that assemble a rolex watch.
