I usually visit this page for treasure pulls it is like 70% accurate: (reason for that being incomplete and somewhat outdated or not referring to pulls from EN version)

but i would really know if there is any official thread where we can see the 100% accurate information about every single treasure pulls or if someone have any better link then the one i provided, would be very helpful.
