F900 "colour" doesn't mean F900 look. It's still a wide colour space, just not S-Gamut.
If you don't use the full S-Gamut there's definitely an argument for using it. I believe in some of their literature Sony actually refer to the F900 as "Alexa" colours, although they probably mean an Alexa in 709 mode.
Alexa colors? Hehehe. So this was first try before 709A.
