I totally get what you mean, upgrading to a larger sensor format,
especially when the image processing pipeline is modern and well-matched, does have a pleasure and excitement all its own. Even on a lesser level, moving from shooting M4/3 for so long to an APS-C Ricoh GR III gave me a bit of that sense, and then the Pentax K-1 II even more so. The below image isn't an exciting one by any means, but the subtlety in shadow, light transitions and colors is just so pleasing to me, especially since it required absolutely minimal PP. I can imagine the X2D is like another level of that.
