I'm looking at those shots on a crappy old laptop, so take this with a grain of salt - but while the GH5 with filters shot looks great in terms of fall-off, it also looks quite soft. Won't all this manipulation make the image too soft (LC, DD1, digital olpf, 1080 upscale)?
I like a detailed, organic filmic image. Not the overly sharp digital look. But I don't want to go too far in the other direction and make it look like it was shot on Betamax with a 35mm adapter :)
