The difference in DR between those 2 sensors is closer to 1 stop and not several stops. Below is a graph comparing the photographic dynamic range between a RX100 (1” sensor) and a GH7 ( M43) at various ISO’s. The M43 sensor gets a boost at ISO3200 but this is not due to sensor size but that specific sensor has dual gain amplification. While the M43 will have better IQ due to the larger sensor surface area, the DR difference is much smaller than you think.The difference isn't minor, a M43 is 93.6% bigger. It's a very very big difference and especially in the dynamic range department. The difference will most likely be several stops.
