Agree with you Glenn. I have seen no evidence that the product changed in any way after the Calibrite rebrand, and X-Rite kept their patch colors for the main 24-patch charts HIGHLY standardized such that the only thing that differs between the 24-patch products (other than one well-documented manufacturing change quite a while ago) is the physical layout of the patches (and even that is minimal).
Note that the chart definition dcamprof bundles for the Passport includes the patches on the other side of the device. If you want to calibrate against just the 24-patch side, you need to use the non-Passport chart definition. (I forget the exact file name and won’t be able to pull it up until tonight, if I even remember to do so when I get home.)
The Passport Photo 2 works great with dcamprof, and WILL generate DCP profiles - I can tell you without a doubt that the bundled profiles in RawTherapee for the Sony A6300, Sony A6500, and Sony A7M4 were all generated using a Passport Photo 2, because I’m the one that generated them.
