I think if you see the specs and compare over more than two stops (mFT/FF), you might see that light intensity plays an important part, nom the size of the sensor.

Here is an old blogpost from lensrentals

Look at the part on aperture on phase detection sensors

"Effect of Lens Aperture

No matter what the sensor type, however, it will usually be more accurate with a wider aperture lens."

Yes, absolutely critical for PDAF. Not so much for CDAF.

And on-sensor and DSLR PDAF are different cases, as explained in my post to him.
