I agree, but what else can it be? If the white data can be recovered it has to have a value 255 or less, because the blu-rays are 8-bit RGB color.
That’s why I said outside of the TV range. Occasionally, there is information just outside of it that one can make a subtle adjustment to recover i.e. a smaller change in levels than that which takes place in the standard TV<->PC conversion.
