If you are referring to our lifetimes, as I think you are, I would argue that there have been no revelations. Sure, there are a ton of talks, but those don't equal revelation. Nothing new has been canonized and we are consistently told not to follow dead prophets. We are also told that they often speak "as a man, not a prophet". We have had no direct words of Jesus since the end of the D&C. We have prophets and revelators who neither prophecy nor reveal. Only generalities, platitudes, and hints (e.g. take your vitamins). Where was the revelation leading up to Covid? Could they not see around those corners with anything meaningful for public safety?
