Generally, it's tough to envision the gap between sensor sizes purely by reviewing a spec sheet. The image underneath will give you a clearer sense of the sensor measurements in the SD10 and A7R IV.

As you can see, both of those cameras provide different resolutions and different sensor sizes. The SD10 having a tinier sensor will make getting shallow depth of field harder and the Sony A7R IV will offer you more detail because of its extra 58 Megapixels. Greater resolution can also make it easier to crop images more aggressively. The more aged SD10 is going to be disadvantaged with regard to sensor tech.
