I don't have either the 200-600 or the a7R4.
Could the reason that it does better on the a9 is because most of you shoot with the electronic shutter with it, and not the mechanical shutter like I'm guessing you do with the a7R4?
It is part of the reason...or at least it does have some affect. I have now switched to using the e-shutter on the A7RIV for all of my non-flight work and that is one of my many small changes to my shooting workflow that I believe has had a positive affect on my success with the A7RIV and 200-600. But it isn't the full solution and isn't the entire cause of the issue.
When you are referring to the e-shutter do you mean real e-shutter, mechanical with EFCS, or total mechanical? The scan rate of the e-shutter on the a7riv is too slow for fast moving objects. Why do you believe that e-shutter has made a difference? You are probably shooting at Tv's greater than those where shutter shock is an issue.
Real e-shutter. Not sure why, just assume it is something to do with the shutter shock. I have experimented back and forth...I put in in mechanical and shot a series of 20 shots of a perched birds, switch to e-shutter and shoot another 20 shots. With e-shutter the % of acceptably sharp shots is higher. This still seems to be happening even when I'm up shooting at 1/1000 or faster sometimes.
