Re: PQ HDR in PNG - draft review

Hi Fredrik,

 ICC version 4.x is too difficult to implement efficiently

Interesting observation.
Does this apply to the mandatory parts or only to the optional parts?
Can you elaborate?

AFAIK PQ or HLG cannot be implemented accurately in ICC v2, as there’s no way to handle overrange.
The v4 para tag enables accurate overrange
