I have posted numerous sample images taken with the same lens and the newer R6II, but I want to consider the older body, which is cheaper, but still has a great performance.
I deliberately shot early in the morning, when the light was challenging and it was quite cold (4degC), and chose to shoot through vegetation to challenge the precision of focus.
Sample shots with the R6II and the RF 200-800 can be located here:

I took myself to the same locations (for comparison) and shot the same subject types. All images were hand-held, available light, with default lens corrections and some noise reduction in Post - using Photoshop at a pretty basic level, but mainly to reduce the images to the correct size.
All using BBF centre spot focus with eye tracking, also BB metering lock, centre spot metering.
Statistically, in terms of 'keeper shots (and eliminating duplicates), the performance of the R6 vs the R6II was not that much different. Now, I was shooting animals not on the wing and those ones may have a different result, but I was getting close to 90% acceptable image - which for the lighting conditions (it's mid winter and much of the environments were in shade and had lots of vegetation clutter) was good IMHO.
