So someone can correct me if I am wrong.
But this would be a function of the lens not the sensor.
Your out of focus light will be better resolved and have more out of focus definition. But it is still out of focus.

Here is a question, the 7D II seems to have a different bokeh from a FF sensor. I never really researched this or thought about it because I discounted it as field of view difference, but is this partly because of smaller pixels?
Will the bokeh from the high mp camera have a different "feel" or "look" to its bokeh because of the increased resolution?
