▲ 3 r/DNA

What actually entails a 3/4 sibling or double cousin reading?

So clearly full siblings are around 50% DNA shared, half siblings are around 25% and these numbers can range, but if a result comes back as two siblings sharing 36% DNA, but there is a suspected paternal father who is the brother of the first father, wouldn't this imply they are not full siblings? Even if the father's are half brother's themselves with different fathers?

I'm not asking for paternity results or anything, I'm just curious about when we assume the lower side of the DNA is still full siblings and when we don't, especially when it comes to a sibling/cousin scenario?
