Sort of. When you have a large amount of details on PC and you sharpen them and bring them to front you get a more vivid image. Red Dead Redemption 2 for example on consoles runs on lowest, or even lower than lowest settings compared to the PC version. When you have no details to start with there is nothing FidelityFX or whichcraft can do to make it look good.
It could help with next gen consoles to a degree, but for this gen i think there is no point in implementing it.
