Bumping to share that I recently reported a scene from ShB (beware post-ShB spoilers) for its poor lighting. And I've got some great news! This is what "working as intended" looks like:

You're not meant to be able to see literally anything in a scene where literally nothing else is going on! :3
At first, this was moved to 'Accepted Bugs', but upon further review, I guess they decided it was fine after all lol. Despite the fact that, as you can see in this YouTube video, the scene had much better visibility before DT -- even considering that the sun is just setting in my screenshots, while it's full nighttime in the video.
