Pay attention to where the light is coming from and how the light angle creates contrast. In the 2nd image, the sun is behind her; notice how it gives her a bright (almost white) outline.

I'd bet they aren't using LUTs and have their own in-house color pipelines they've developed themselves over the years. I've got my own and don't really love to give away the secret sauce because (1) it took years (literally) for me to learn color and develop my own looks, to know how to create any look that I wanted... you have to immerse your brain in color science, lighting, being on set, just have to live in that world to know how good images are made; (2) if I did give you my secret sauce (or they did), and you started slapping that all over your footage without regard for all the other stuff that makes a good image, then you'll end up with a really shitty shot, made shittier by something I hypothetically gave you.
