That is only true because you resize the image. Smallers pixels lead to smaller noise, once resized from 36mp to say 16mp for print output noise will be pretty much absent, however it is not the result of your sensor getting 4x more light than m43, it gets the exact same amount of light per surface area.

I see most people do not grasp this concept so lets read it from the people who make the technology:

If you don't get how pixel size affects noise and Dynamic range after that I don't know what will. If you don't get that sensor size does not affect DR and noise after that I don't know what will.

I'm out, have fun reading.
