The thing that stood out to me most was the difference in bokeh. I don't like what PL5 has done with that. Did you dial up the microcontrast?

Good points. I had the microcontrast set to 15, which is my default, and what I thought roughly matches the clarity setting of 25 on LR that I use as a default. But it's entirely possible that the other lens corrections on PL5 mean I just don't need as high a microcontrast setting. I went back and redid one of them (the 56 center shot), lowering the microcontrast to 0, the midtones contrast to -16, and the ClearView Plus setting to 10 (from 20, which is my default, and what I thought roughly corresponds to the dehaze setting of 25 that I use on LR).

So here is the 56 F1.4 center shot again, first LR then DXO:

Now here's the reprocessed DXO version:

And here are the 100% crops from the two DXO versions, to see whether the adjustments to help the bokeh had an adverse effect on detail:

This just goes to show how difficult it is to match settings between processors. It's entirely possible, of course, that the extra detail you get with the DXO lens corrections comes at a price of less pleasant-looking bokeh. But it does seem like there are some things you can do to compensate for that.
