The dark side - I've been there

But you don't have specific results of THAT Canon lens, do you?It's much better than assumption because manufactures uses the same software when they design something. I assume they wouldn't bother building a test lens if the result looks bad even on paper (to save cost of development). Simulation results of 'real lenses' seem consistent with their shooting performance too.
And result like bokeh is pretty straightforward I think.

You just need to set your own reference lens for "good", "acceptable" and "bad" performance.
