So someone at Reddit posted this interesting comment in regards to my inquiry.
I think it might be the way the preview works.
The preview probably compares the position of your character to the position of your cursor. The actual attack likely uses the position of your character and the anchor point of your target.
This likely isn't the full story, but it might be part of it, judging from how I was getting advantage/normal roll previews based on nothing but moving my cursor around the enemy model. It made me think back to that one specific bug that Larian kept emphasizing in the patch notes. Three times to be exact. That whole thing about the one NPC peeing higher than should be anatomically possible from a visual perspective.
What if a different but similar version of that is at play here? As in, perhaps the previews are accurate, the real issue might be that the game could be reading our positions incorrectly upon launching an attack (as in, calculating our characters to be slightly higher in elevation than we actually are)? It would explain myself being able to get advantage rolls when the preview says I shouldn't, and it would also explain disadvantage previews resulting in a normal attack roll at the same time. A widening of the break points should mean that it would be harder to get a low ground disadvantage penalty AND a high ground advantage bonus at the same time. But I have not observed advantage previews turning into normal rolls throughout any of my tests, only the exact opposite.
Of course, that also brings up the question, why does this possible bug favor only us? To which I would answer that it's not really just us. The calculations probably only adjust the attacker upwards, not the defender, and we don't get that much visual data about how the enemy AI calculates high ground/low ground.
