Your question seems to imply that the only thing involved in the final "look" that software provides for a given raw file is a color profile. This is simply not the case. The look from one package cannot be achieved in another package through color profiling.
There is no "one true photo" inside a raw file that you simply "open" with compatible software. Every major raw convertor has it's own proprietary math. Just look the improvement between newer/older versions of the same software to see how much this math matters even when the color profile remains the same.
The above is not to say that you can't get closer to the color look you want in any given package by playing with different profiles, profiling, or profile editing.
Not surprisingly, you'll find many people find the best color/tone/look using [software + hardware] from a single source, as they:
- know the hardware the best (they can literally walk down the hall and ask questions as needed)
- can influence each other during the design/prototype stage (e.g.
IQ250 development)
- are financially/professionally as well as personally motivated to spend as much time as needed for a specific [camera+software] to look it's best
Of course it is subjective, so the most important lesson to take away is to try multiple raw convertors and consider the entire package (software + hardware) whenever making a purchase/rental/etc.
