One noteworthy confound is the strength and design of the OLPF / AA filter. Canon has stated that the 24 MP sensor in the R3 delivers greater spatial resolution than the 30 MP sensor in the 5DIV. In other words, not all megapixels are created equal.
20-25 MPs
25-30 MPs
30-40 MPs
40-60 MPs
>60 MPs
<20 MPs
Why one? Two bodies, the R3 at 24 MP and the R5 at 45 MPs
Why one body? I want multiple sensor resolutions and I will explain below.

I remember EOSHD website person took the aa filter off the 5dIII and it seemed substantively sharper. Now that I have an R5, toying w/ turning the 5d3 to full spectrum, though the more I research it the less likely I am going to do it... now that we are talking about the sensor stack.
