How do I reverse a photo effect?

I'm sure someone on here will give far better info but...

The Samsung description of what the mode does is a little vague. That said and assuming there is no simple "this undoes it" option, id go for reversing any odd colouring/contrast or whatever using an app.

What effect has the mode added to the picture that you wish to reverse?

Can the pic be posted on here? (Unless it's a cock shot and Samsung food mode auto added a bun and ketchup obvs.)

I think food mode blurs the edges of the pic, so once embedded, pretty hard to undo I'd imagine.

Had a look on my S22 and can't see anything that looks remoteley obvious

Tried this on an S20, couldn't find anyway to do it, the filter was applied to the original image.
Could probably reverse it if it had been applied on a proper photo editing suite, but not a camera filter.

Could you use stable diffusion and inpainting to create something akin to what you started with?

Not tried it myself so no idea if it will work.
