By default, Jay pretends that the display uses sRGB primaries. This is also how
most other systems behave. In reality, most displays use a much larger gamut. For

is interpreting colors in their native gamut, then colors will appear more

If this is set to `true`, Jay assumes that the display uses the primaries
advertised in its EDID. This might produce more accurate colors while also
allowing color-managed applications to use the full gamut of the display.
