In many cases, it is very tough to imagine the contrast between sensor sizes merely by reviewing a spec sheet. The picture here might offer you a far better sense of the sensor dimensions in the 5010 and A7R III.

Clearly, both the cameras have different megapixels and different sensor sizes. The 5010 having a tinier sensor is going to make shooting shallow depth of field trickier and the Sony A7R III will deliver more detail having an extra 28MP. Higher resolution will also allow you to crop shots a bit more aggressively. The more aged 5010 is going to be disadvantaged with regard to sensor innovation.
