have a nice read.

the important part is there focus on CRT. so it'S supposed to be used event through we clearly know they didn't look at bt 1886 well we also know they did because bt 1886 is gamma 2.4 on perfect black displays. and on none perfect black display like CR 1000 it is even brighter in black parts then sRGB is.

i can tell you they didn't use the bt 709 curve (they are not supposed to they where using what ever they want) the spec even warns about using it for an EOTF:

In typical production practice the encoding function of image sources is adjusted so that the final picture has the
desired look, as viewed on a reference monitor having the reference decoding function of Recommendation
ITU-R BT.1886, in the reference viewing environment defined in Recommendation ITU-R BT.2035.

it's an encoding function anyway not a decoding function like gamma 2.2.
