This is what I was talking about earlier with the rose tinted glasses thing. You're saying that Bloodborne has this pro but you don't recognize that DS3 has the same shit. You're entirely biased.
None of the things you listed are actually part of the main quest. They are things you find as you play the game. You are told to just hunt. That is the only direction they give you until you kill Micolash pretty much. "Go to hemwick crossing and wait for a ride to cainhurst." Okay I've got one for DS3 "Get the Path of the Dragon gesture and use it at the dragon statue." Or "Cut down the bridge in Catacombs of Carthus and go down to the Smouldering Lake." Those are secrets by the way. Not the main story.
All that stuff about Bergenwerth and the Healing Church is the lore. Not the story. The story is what you're doing. The lore is why you're doing it and what secrets the various characters and locations hold.
But okay, they do allude to you needing to find the spider. But what does that accomplish? Okay you're lead to the Nightmare of Mensis but what is the purpose of you being there? What is the main character of Bloodborne working towards? You don't know until you kill Mergo pretty much. They string you along with clues but you never know how close you are to being done.
The choice at the end is the perfect example. In Dark Souls 1 you meet Frampt and Kaathe and through speaking with them you can then decide how you want to end the game. The choice itself doesn't matter because the cycle will start anew, but you still feel educated enough to make the decision. In Bloodborne, Gehrman says that he can end your life or you have to fight him. Why would I let him kill me? What would that accomplish? It's sprung on you at the last moment and you have no real idea what you should do because there's no context for it.
The reason that Dark Souls works is because it gives you a good surface level idea of what the world and characters are about and then through research and speculation you can learn new things about them. Bloodborne is very vague and mysterious which results in me being wholly uninterested in the lore of it. The reason I find Ludwig so interesting is because you see his weapons and you hear how he was one of the first of the hunters. At the very least even if you don't read the descriptions, you see his name on these weapons made for humans but when you see him, he is a hideous monstrosity. That makes him interesting.
If he was just a hideous monstrosity with no overt backstory (like One Reborn for instance) then I wouldn't care about him. Subtlety is fine but too much just detracts from the experience.
