You can fail and die in different ways in Disco Elysium.
On the other hand, death won't end your playthrough in any soulslike action RPG.
Party wipe is not a gameover even in such a renowned classic as Planet Escape Tournament.
So by your own standards, Disco Elysium should be more of an RPG than Dark Souls and PST.
Considering Dark Souls and PST to be alike... Now I'm triggered.
You can die in platformers and FPS, you can fail in cooking, fishing and golfing games.
It doesn't qualify them as RPG.
The character creation alone tells you Disco isn't a RPG.
Sure, they worked hard to make it look like a dumbed down one, just like 50% of the games you can find on steam but if you can't tell the difference, maybe you don't like RPG.
