you cant shoot both cameras at the same fstop, different sensor size (and even if they were both ff or apsc, you still cant shoot same fstop, you will get different results with different cameras at the same fstop, even with the same camera make/model) without a light meter and greyscale, these camera comparisons are pointless, especially so ones that were shot outdoors.
and two:
ive had a d750 and a d850 and what i have to say here is that youre either 1.lying, 2.have a crappy lens or 3. use shitty settings. why do i say this? because none of these images look like something a d750 would pop out.
look at pic related for example, image even has blown out highlights and yet look at the night and day difference in color graduation and tonality within shadows and highlights in your images compared to this... its a night and day difference. thats why i say youre either lying, have a crappy lens or just use crappy settings
