The ASI6200/QHY600 apparently have some hardware binning.
On the QHY600 there are different readout modes. One of these extends the full well depth. I don't think that is only virtual in that case. This is one of the main QHY advantages, these different readout modes.
But its something I will keep an eye on as I started using the extended full well depth and it seemed to hold highlights better and reduce background banding.
