Ignore the 0.061. I opened your file and let it overwrite my preferences, but apparently the black override remains from before.When I choose BT.1886 I still get a flat gamma target. Can you post your References Preference pane please?
EDIT: I'm catching up. If I stay on black compensation gamma and override black with 0.061 from the target Y value in the black reference measurement I get the RGB values you shared.
So my next question then:
- Where did you get 0.061 from and what would you expect to see it at? Presumably much closer to 0?
- If I change to BT.1886 with 0.061 applied my measurements are now very far away. Is it better to correct from where I am, or reset and start again?
If your black measured 0 (either true black, or meter limitation) then BT.1886 is indeed the same as gamma 2.4.
