That's pretty vague. What sort of profiles ? What information do they contain ?
Well, there is not much in depth information. But this is a fair description of what is going on:

I'll send them an email with questions of the profiles.

When you say the DTP94 is better for refresh displays you get me a bit 
confused. I will be
calibrating refreshing displays only. I.e a plasma TV, a PC monitor with led 
backlight and another
with a PVA display (for photo editing) and a Home Theater LED based projector. 
Are you saying the
i1d3 is not a good option for these displays? Or do you by refreshing displays 
mean CRTs?
Anything with a non-constant light output is more subject to variations
due to the fact that the i1d3 isn't capable of detecting or synchronising
to the refresh period. The DTP94 is capable of this.

It's easy enough to examine this - take the same reading over and
over, and see how much it varies.
Hmm, one of their selling points (CP) is that the meter has very stable readings, even in very low light. Maybe they are reading several measurements and getting an average?
First question. Is the Chromapure PRO bundle with extra reference calibration 
really necessary in
practice or is it just advertising fluff?
Given the close comparison with the Discus, I get the impression that anything 
that a standard i1d3 + display .edr/.ccss file is probably not buying much.
Do you provide standard calibration files with the i1d3 driver for Argyll?
