Requested feature: PSP colour space profile for Retroarch Vita?

Hello! Thanks to all those concerned for their amazing work on retroarch for Vita!

I apologise in advance if this is the wrong place for a request or if the request itself is unrealistic.

I am using retroarch on an OLED Vita for certain games / emus that perform better than in Adrenaline. The tradeoff to this for me, first world problem though it may be, is that the games’ colours can look really oversaturated due to the OLED Vita’s colour space, to the point of being garish. This is not an issue in Adrenaline as PS1 and other emulated games appear to default to the PSP’s colour space.

I was therefore wondering / hoping that it might be possible to somehow add an option to use the PSP colour space or else limit the existing one to equivalent levels similar to how when playing PSP games natively on Vita, you can choose between the PSP colour gamut or the Vita native colour space. . . ? Or is that feature tied to the Vita’s built-in PSP emulator only?

Many thanks for your time.
