Oftentimes, it is very difficult to see the contrast in sensor measurements purely by viewing specifications. The graphic below will provide you a greater sense of the sensor sizing in the CX4 and A7R IV.

Plainly, both the cameras feature different megapixel count and different sensor measurements. The CX4 because of its smaller sensor will make shooting shallow depth of field harder and the Sony A7R IV will render greater detail as a result of its extra 51MP. Higher resolution will also let you crop pictures way more aggressively. The older CX4 will be disadvantaged in sensor tech.
