I now have a decent set of test files. Sunlit window scene with shadows and a range of colours. Shots taken in 100/100 up to 100/3200. Three sets, exposing for ISO 100: "ETTR-ish" (about 1 stop overexposed?), 2-stops under, and 4-stops under (this one includes 100/6400). Why under? Because Walter took a look at the first set and said they were weird; good highlight recovery but not much change to dark areas. So perhaps 200D prefers it the opposite way to old cams.
If you want to compare, DM me for the links. It's about 250MB per set.
