MaxCLL avif - Adobe Cameraraw

Hi Adobe team,

Could you please provide more information on how the MaxContentLightLevel is set when creating an AVIF file from Camera Raw (HDR workflow)? It seems that they are not correctly computed, I've noticed some unusual values. These values are causing weird behavior in other viewers, such as Chrome, which takes into account the MaxCLL value to render the image and adapt the headroom.
My settings are set to ITU-R BT.2408 (203/1000 nits).
I'm using the Windows version of Adobe Camera Raw with the latest update 16.2.

Thanks a lot,

JM
