All true.
But here is where DVX may be appropriate. Because I think (I may be wrong) that most users here are delivering to web not as an 'auxiliary' but as the main platform.
I feel lack of those should not be a dissuader for those wanting to bring the best from ones footage.
..argument.. you can't know precisely what you are doing to your footage.

Scopes will help you know if your own set up is way out of whack so there is some 'precision'
Many DVX users, however, have in interest in moving their footage to a better place and that is where a board here would become relevant..
seems it's not really a good choice, Steve Shaw has a good forum that discusses all things callibration, and it gets no love there;

alternitivly, there's offers on basic callibration software and probes from both Light Illusion and CalMan..

and they can both use this inexpensive probe;

Judging from the interest in this thread, I am willing to give it a go:
