To sum up, the two cameras offer different megapixels and different sensor sizes. The A7R IV having a larger sensor will make getting shallow DOF easier and the Sony A7R IV will show greater detail with its extra 47MP. Greater resolution will also help you crop pics a little more aggressively. The newer A7R IV will have an advantage when it comes to sensor technology.
