Big problem I see with this new app, from what I've read, is the target aim points are fixed. I suspect we need full control over at least white balance, the ability to enter CCT Kelvin values to tweak the WB to produce a match. My understanding is you're 'stuck' with a couple presets (D50, D65 etc). Once again, did X-rite dumb's down the product for the market, instead of providing tools to make the product work better for more users?
It's dumbed down. The good news is that it seems to work, at least with iP5 and i1Pro2. It calibrates TRC to unknown target, and you can switch between D50, D65 and Native wtpt. The created profile hits the X-Rite Profile Cloud, so you can't play with it in any gamut viewer.
There are two other features that initially took my attention - soft proofing, and ambient light correction.
You can only soft proof using a couple of standardised offset press CMYK profiles, so not really all that useful for photographers. There's no possibility to use custom ICC profiles, or I'm too stupid to find the way how to do it. No paper white/black ink simulation either.
As for ambient compensation, I didn't see the difference that I expected, no matter what setting I used. There's a noticeable saturation change, but I can't see any significant TRC change.
