I used this theory to create a 3D LUT that does exactly this fix, to be applied to images in sRGB colorspace: https://mega.nz/#!byBj2YBA!ZawROR_rbKu98...bsulCYLP4Q
The results might be slightly off for Rec709. I'm not entirely sure what the differences are between sRGB and Rec709, but either way, this LUT should work reliably for sRGB, so make sure that's the color space you're working in for ideal results.
