IMHO much of the so called "Leica Look" is simply due to images coming from some very talented photographers, who not only are skilled at composition, but also post processing.
Exceptions apply of course, but for the most part, those who want to invest what is often tens of thousands of dollars on this hobby, especially with a RF camera, are pretty serious enthusiast.
Your simply not going to see a lot of total beginners posting straight out of camera cat pics like you do from plenty of other mass market consumer cameras.
Take a poster like Charkles K for example, Beautiful Leica images, but he posted some images taken from a little Sony RX100 and darn if they didn't have a fantastic tonality and web sharpness that we are used to seeing in his Leica images.
There certainly are some fantastic optics in the Leica lineup, but there really is no out of the box magic. Trust me I know, I've owned a M8.2 and a M9 and plenty of nice glass and very few of my images had the "Leica Look"
Its about great gear yes, but if you don't have a great eye, and some good skills in post, your not going to get those "WOW" shots.
Likewise, those that really have a good eye and know their way around LR or PS, can often produce images that just jump off the screen with beautiful color and depth.
