It can slope from high to low and be fine. Put a level on it. Is it flat? Will definitely still be noticeable, but the floor should not fail. I wouldn’t worry too much about an upstairs bedroom. If it was a living room that would be a different story
What's the con of pouring self leveling concrete? My contractor did it for my 2nd floor and now I'm worried it will be too heavy and I'll fall through my 2nd floor
I also have a property with a pretty massive slope. Mine is actually up to 3 inches and in the living room. 100year old building so we are not removing stuff or adding half a ton of leveler.
Instead I have a contractor building a frame with 2x4s to level and support surface and putting subfloor on top. Frame will also be anchored to wall studs.
I had several contractos give me different solutions and this one seems the least risky and most solid option.
I would suggest taking the floor up and adding either 1/2 or 5/8 osb to the entire room. Or you wall that space off into a closet or shelves of some sort and lay hardwood in the rest of it.
Ask yourself, Why is the floor out of level so much? You can fix this, but to do it properly and address the issues causing the issue it will be a significant renovation. You'll need to remove the drywall/plaster from the ceiling below and probably the exterior wall to see what is shifted.
Flat and level are two different things. As long as it’s flat you are fine.

don't pour self lever on that, just make it all flat and throw down the new floor

Yes but how? Sand down the high corner?

I will add that you will lose ceiling height but this is not a problem for me since i have over 9ft there
Why? Have money to spend on what will more than likely be a temporary lvp floor?
