Answering to this one specifically, I think the analytical inverse is important for many things. Some use cases:
- Adding logos to images while preserving their appearance.
- Pushing smartphones video feeds in Unreal Engine or Unity without having them affected by the tonemapper.
- Bypass the RRT + ODT entirely and still being able to push an in-house view transform with a LMT into the ACES system.
Cheers,
