Take your sample and stretch it hard, and drag your fingernails across it - that's how it will look over time. Or you can look at this ottoman I have in my home, its was the floor model in my store for three to four years and had hundreds if not thousands of purses and leather handles dragged across it, as well as dozens of kids playing on it. This is in Tuscany Harness, but its performs the same as Tiburon in looks, feel and appearance. Your samples have not been handled and stretched, so go to work on them!
And this is what Tuscany Harness looks like when its brand new - this sofa is in my store if you are close to Wash DC and want to take a look:
These are fine Italian pull-up hides, but they DO have a waxy topcoat surface so if you are looking for velvet smooth they are not for you. They will always show pressure marks that will increase over time, and either you like that look or not. They are are their best in a tufted surface as well. There are not problems with this class of hides, though
there ARE lots of mis-understanding of what they are. Many people object to the slick surface and markings, but that this shows this leather is not for them. A good Italian pull-up is a remarkable leather, but you have to know what you are buying into. It sounds to me you are not familiar with this type of leather so I'm going to suggest that it may not be for you.
Excellent choices in the frames, but perhaps consider Weston, Capri, Arizona, Quintessence if you want a fine leather that looks consistent day after day. The polished leathers are really handsome as well, though they will be more 'crusty' to sit on.
