Unlike monitors which are light emissive, gamut shrinkage is an intrinsic property of reflective media. Such media creates colors only through attenuation of spectral frequencies. Yellows are the least affected because high saturation yellows need only attenuate blues which contribute little to luminance.
The Sun's luminance, about 500,000,000 cd/m^2 when low in the sky like in the image, is about 5 orders of magnitude greater than the luminance of reflected light from surfaces on the Earth.
I can't offer a solution other than Photoshop manipulation and soft proofing to create the most attractive result.
