primary color space probably comes from: https://glenwing.github.io/docs/VESA-EEDID-A2.pdf - "Standard Default Color Space - sRGB: If this bit is set to 1, the display uses the sRGB standard default color space as its primary color space. [...]" and it doesn't define primary color space ;)
cpli, you should not be able to call wl_log() at all, it is not exported.
mceier, yes, the doc for 'bool srgb_is_primary;' is what made me ask. :-)
