As you can see, both the cameras enjoy the same exact sensor sizing albeit not the same resolution. You should expect the Sony A7 IV to render extra detail due to its extra 21 Megapixels. Higher resolution can also allow you to crop photographs far more aggressively. The newer A7 IV will have an advantage in sensor innovation.
