"Color accuracy" is a bit treacherous thing to check for when it comes to camera profilers.
A good profiler makes a tradeoff between smoothness and measurement point accuracy to secure good quality gradients and transitions between colors. You will also need to relate to measurement errors. With DCamProf this is partly done automatically, but I'd recommend to do some manual steps too. DCamProf is aimed for users that have a special interest in profiling or otherwise is prepared to spend quite some time, reading and experimentation to achieve a great result. Although you can make a profile with a fairly simple workflow, it's not how you make the best out of it.
One of the major features of DCamProf is its neutral tone reproduction operator which can turn your colorimetric accurate profile into something that actually shows sane colors with a contrast curve applied (colorimetric profiles will make garish results with an RGB curve). This throws "color accuracy" out the window though, as it's only defined for colorimetric applications, eg reproduction work.
For reproduction work in strict copy conditions I'd recommend a 3D LUT profiler and custom targets. The colorimetric part of DCamProf is 2.5D for reasons described in the docs, and I don't plan to change that. The tone reproduction operator is 3D though. Anyway the 2.5D design limits the peak colorimetric accuracy that could be had in scanner-like conditions.
As far as I can see DCamProf is more of a specialist tool, including advanced features such as SSF profiling, supporting custom targets, flatfield support etc, while camprof aims at a broader audience, is much easier to use, is self-contained (DCamProf requires Argyll) and has more automation.
