Often, it can be difficult to envision the difference in sensor sizing merely by researching specifications. The photograph here might give you a more clear sense of the sensor dimensions in the 1 and A7R IV.

Plainly, the two cameras come with different resolutions and different sensor sizing. The 1 using its smaller sensor will make achieving bokeh more challenging and the Sony A7R IV will provide you with more detail with its extra 49 Megapixels. Greater resolution will also make it easier to crop photos a good deal more aggressively. The older 1 will be behind in sensor innovation.
