Normally, it is very hard to imagine the gap in sensor measurements purely by looking through technical specs. The graphic underneath will help offer you a more clear sense of the sensor dimensions in the EX-Z450 and DP3 Merrill.

As you have seen, each of these cameras feature different megapixel count and different sensor measurements. The EX-Z450 due to its smaller sensor is going to make getting shallow depth of field harder and the Sigma DP3 Merrill will render more detail due to its extra 3MP. Higher resolution will also allow you to crop shots way more aggressively. The older EX-Z450 will be disadvantaged in sensor innovation.
