In Game Re-shade Settings

As a PS5 player, I'm super jealous of PC players over their ability to re-shade the game using third party software (whether Square deems this legal or not is a separate issue) until I noticed something... FF14 already has re-shade settings built into the game! While taking a gpose photo there are a ton of lighting settings unavailable to actual gameplay. Why is this? While some of the camera filter settings would be a bit much to actually play the game with, many make the game look so much better without compromising readability. I'm not a game dev so I don't know how difficult it would be to enable these camera filters during actual gameplay but from my perspective it doesn't seem like this would be too difficult to implement. I think many players on PS4 and PS5 as well as PC players who aren't comfortable modifying their game would greatly appreciate this feature. I couldn't find anyone on the forums or elsewhere talking about this possibility so my hope is that this idea makes it in front of a dev somehow.

Maybe it has to do with a potential performance hit? I know when I activate gpose my frame rate drops about 10fps. That may be due to the depth of field though. I know the base PS4 does not have much wiggle room for performance. However, it would be a cool optional thing to add for players!
