Is spectators territory estimation supposed to be this bad?

Does the AI score estimator not understand ko?

After a recent game involving a ko fight, I noticed that the post-game score estimator seemed way off. I was able to replicate it on a demo board: [Screenshot_20211114-222805] Black just played (and captured) at D5. White can’t possibly have any ko threats here, right? But the AI gives the ko to White anyway. What’s going on?
