I'm on a Vivo X300 pro in a dim room, max brightness. Some of these looked impossible but then suddenly I'd see the line.

Same score here on my MBP with an absolutely filthy screen. Reckon I could top the leaderboard if I cleaned it.

Same score and setup. Overhead lights were messing with me a bit as well as the vignetting in the browser. I wanna get sub 0.0030 now

Replying to myself. I also tried this with both my Samsung S25+ phone and LG G5 TV and repeatedly scored in the 0.003-0.005 range on both so it doesn't seem like the display makes that much of a difference for me.
