Hi
as DCI-P3 seems to be important these days to compare tvs from and how much of the P3 gamut they can reach i just want to know what the coverage would be like here.
can someone calculate the P3 % coverage from this gamut it would be great.
DCI-P3 x and y points xW yW xR yR xG yG xB yB DCI-P3 D65 0.3127 0.3290 0.680 0.320 0.265 0.690 0.150 0.060Hi,
the easiest way to get P3 coverage with DisplayCAL is to just re-calculate the profile (menu “Options”, “Create profile from measurement data…”, select existing profile).

that cant be right
i have 125.4% SRGB coverage but only 88.8% DCI-P3 ?Red is close to target with P3 already
its only green that is lower.i guess it depends how you calculate the gamut volume.
if its its size or how close it is to P3 primarys?i mean the gamut can have the same size but have an offset to P3
still you get an lower % i guessthat cant be right
i have 125.4% SRGB coverage but only 88.8% DCI-P3 ?Why wouldn’t it?
Red is close to target with P3 already
its only green that is lower.You can’t judge that from xy chromaticity alone. You also need to look at the (relative) luminance component, and ideally you do that in a space that’s (atleast somewhat) perceptually uniform (xyY isn’t good for this either, DisplayCAL uses CIE L*a*b*).

where is the problem with luminance ?
it cant be betteras i said
RED is close to DCI P3 target alredyyour calculations for gamut volume must be wrong
i need to check with other calibration programswhere is the problem with luminance ?
The problem is that it’s missing from the chromaticity information you posted. Color spaces are 3D objects, trying to calculate coverage in 2D is a futile exercise.
RED is close to DCI P3 target alredy
You can’t know this from just xy chromaticity.
your calculations for gamut volume must be wrong
i need to check with other calibration programsBelieve me, there’s nothing wrong there. If another program uses just chromaticity to calculate gamut coverage, then that is the problem, for the reasons outlined.
