A profiled camera is required if you have to produce the exact same
colour of an object under different lights (outside in bright sunlight
or in the shadow of a tree or in your studio) with different lenses and
different cameras. This requires an exact white balance setup and a
colour profiling.

As an example: If you want to document the change of colour of a subject
you have to make sure that the colour in your photo has a reference (the
ICC profile and the base target you used for profiling).

But If you see photograph as an art and your personal way of seeing
things profiling is wast of time. It is wast of time if you don't use a
exact profiled monitor (and with this I mean monitors in the 2000€
range) an profiled working environment (lights around your monitor) and
a profiled printer.

IMHO the first step is to profile your monitor and use labs using
profiled printers (and share their printer profile). Profiling your
monitor is not that expensive (about 100€ - 200€). For this you have to
use at least a monitor with IPS or VA panel and about 95% match of sRGB
gamut.

Yust my thoughts
