Inconsistent DoVi Pictures

I have issues playing some DoVi videos from Plex and Jellyfin with Infuse.

Compared to the native apps, colors appear to be more vivid in bright scenes and dull in dark scenes. Also in some cases, the overall picture gets brighter, returns to normal, and then gets brighter again.

These are TV show episodes videos and I see that they have P8. I’ve tried to change the Extended Dolby Vision settings, but it’s the same with Auto and Limited, while Off seems to disable DoVi and play as HDR instead.

There’s probably something wrong with these videos. But is there any setting I can change to fix this, both on Infuse and Plex/Jellyfin?

TvOS 16.6
Infuse 7.5.9
