Gamut errors programmaticaly detection

Hello!

I want to detect Gamut errors in file. And I try to use OpenCV to do it.
Accordinally EBU R 103 V3 (https://tech.ebu.ch/docs/r/r103.pdf)

Gamut Errors need detection if the RGB components and the corresponding Luminance (Y) signal exceed
the "Preferred Minimum/Maximum" range of digital sample levels

"Preferred Minimum/Maximum" range is [5, 246]

But any black pixels decoded with OpenCV has (0,0,0) values

Please help me. Maybe I'm misinterpreting the standard?
