Could you precise what you think was better in the first picture and where you find less details in the second one?
On the Gibraltar rock, the rendition of the trees and rock has improved, secondary road non existent lighting has been removed or reduced, water reflection have been added, about clouds we are not comparing the same weather but they look great on the new picture.
My guess: the first picture has more artificial lights, maybe those are the details you find missing in the second one.
