HDR tone mapped to SDR randomly

When playing Aces & Adventures in HDR using Special K v22.9.6, OBS v28.0.1 will properly display it in HDR, but after a few seconds, it will start tone mapping the game to SDR.

The game capture is already in Rec. 2100 (PQ):

I tried a bunch of different settings, and it seems like hiding and showing the game capture fixes it, but a few seconds later, it's back to SDR mode.

I'm wondering why it randomly turns on the tone mapper for SDR when receiving HDR content and how I might fix it.
