I bow to those with better eyesight than I, but as regards DR I find very little at 200 iso that is immediately and perceptively better than at 100 iso (which is where I tend to stay). Others may (and do) disagree so test for yourself.
However the steep part of the learning curve for me lies in the interaction between SPP and Lightroom. Be aware that, as far as I know, SPP is not properly colour managed. Further both the DP2&3Ms (which I use) work best when well exposed. SPP does allow some highlight recovery but be alert to the fact that the warnings in SPP do not match the highlight warnings in a 16 bit Tiff exported to Lightroom in Profoto colour space. The SPP warnings are much more conservative and if you reduce exposure in SPP to what it says is not clipped you can end up with a pretty ugly file. What SPP says is clipped is not necessarily the case when you look at a Profoto Tiff file in Lightroom. Also avoid the heavy hand on the fill light feature. This can also compress highlights in a very ugly way.
These little cameras can produce truly exceptional images. But they need careful handling when you are dealing with subjects with wide dynamic ranges - that only comes with experience and experimentation. My advice is don't trust SPP to produce a perfect (or near perfect) file based upon what it shows you. Learn what the differences between the SPP screen shows and the exported file actually looks like in your editing program of choice and adjust accordingly. It is not too difficult but it does require practice and experimentation.
