Just completed a short video discussing some key differences that I have found whilst shooting wildlife with the 5Dm4 and the 5Dmk3, both of which I own.

Whilst I have not found that there is any one aspect of performance that is radically upgraded between the two cameras, (aside from Live View shooting of course which is so much better on the new one), there are so many small advances and improvements that, the 5Dmk4 just does the job better. Of the improvements, I find the better image quality and improved low light capability perhaps the most useful, for my own wildlife shooting needs.
I am finding that it I can comfortably use iso 3200 anytime I need faster shutter speeds in low light, and even iso 6400 for print, with some noise reduction.
