Can This Hack Really Turn Your LUMIX S9 Into a Leica?

As a longtime Leica camera user, something that I've always wanted was a way to make the images from my Leica SL2s look a lot more like something else. Specifically, I would've loved some sort of Leica Look support for the camera. Thankfully, Leica kind of gave it to us by uploading images to the Leica Fotos app and then applying the looks there. It's really not the same thing as doing it in-camera or even in Capture One. But I'll admit that they did it. However, I stumbled on the work of one internet sleuth who apparently found a way to bring Leica looks to LUTS. And those luts can be loaded onto LUMIX cameras like the Panasonic S9.
