Thought FF (k1) would give me. Significant increase in light gathering vs k70

Hello everyone. I was under the impression that an FF would increase the shutter speed at the same fstop and ISO given that the sensor gathers more light when using the same lens. And that ISO on crop was actually equivalent to 1.5 FF ISO. So I went ahead and purchased the k1 and compared it to my k70. It turns out that nothing changes and to my eyes, high ISO performance up to 1600 is pretty much the same. Where exactly is the advantage of investing 4x the dollar amount except for the 36mp output. I used a sigma art 18-35 on crop k70 @ 18mm and the same lens on its equivalent 28mm (perfectly usable with little vigneting. Any thoughts?
