the second OETF corresponds to a hybrid gamma OETF,
the first value is to be referred to by a decoding device that does not support the hybrid gamma OETF,
the second OETF is a combination of a square root function and a logarithmic function,
the SEI is provided in a multiplexing layer other than a video coding layer, and
the second OETF has compatibility with the first OETF.
