Description

Currently, seems we only have builtin conversion for REC.2100-PQ/HLG with 100nits reference white. However seems BT.2408 requires 203nits as reference white.
So how to implement a conversion for 203nits version of REC.2100-PQ/HLG?

Research direction

The issue names no file, test, or entry point; start by locating the built-in REC.2100-PQ/HLG conversion and reviewing how its 100-nit reference white is represented. Compare that behavior with the BT.2408 203-nit requirement, then define and verify a supported 203-nit conversion.
