Christie doesn't offer a specific set of "Post Production" projectors. I'm also not so sure what the Barco "-P" series brings to the table, besides a "high contrast lens", that's also available for their normal DCI projectors. It includes an ACS-2048 alternative content switcher, which is, as far as I'm informed, end of sale and if you're a post production house, you probably have lots of other means to route alternative content to your projector already...
In any case, I would always go for a 3DLP setup for DCI color grading, so that eliminates Sony. Although some chains are squarely in bed with Sony, TI 3DLP 2K setups have the biggest install base.

It's essentially a DP2K-B / DP4K-B series projector, they also come with 1.2" DMDs. I somehow doubt that they built a custom light engine for a device with such a small target market.
From what I've been told, (and yes, that info might be incorrect or incomplete, so feel free to enlighten us), it's essentially a normal DP2K/DP4K projector fitted with a "high contrast" lens right out of the box, a customized version of the communicator software, an End-of-Sale input switcher as a "free" giveaway and it has been tested to meet higher specifications. So, essentially the best of the batch are destined to become a "P-series", while the rest is good enough to become an ordinary DCI projector.
So if this is just it, I'm not sure if this is really worth the premium.

I guess it would, but there's so little money in good sense, so just let's not talk about it, ok?

Hitting the primaries is just but one step in the color grading process. How is it when the level varies (look at the colors on a step chart, look at the greys on a step chart...etc.
A popular misconception for some with NEC NC900C is that one can remove the notch filter, reshoot colors and you are good-to-go...NO! Primaries are primaries...then end points but do not depict how the system will do between. Without the notch filter, it will no longer be as uniform.
This is the same, wrong, line of thinking that has people putting high-gain screens and setting the center to 14fL and thinking they have made a bright picture with less light. The spec is not JUST 14fL in the center but there is also a uniformity component to the spec too and if your screen gain is above 1.3 and flat, it will never achieve it and your image will be DARKER than spec.
Again, it is my understanding that the entire light path is improved on the "P" series to achieve its higher contrast. I suppose one could look on the parts lists to see if there are unique parts on the P projector versus the standard "B" projectors.
The Software (Post Production) works on ANY Barco based DCinema projector, not just the "P"...in fact, Post Production goes all of the way back to the DP30, 40 and 50 days. It's chief addition is a more detailed PCF section where one can make their own TCGD files, PCF files to hit desired color corrections for particular projects. It also blows out the potential presets up to 99 and their is an extra column of test pattern presets. Also, it was first to have a "dark display" color scheme so your laptop wasn't as bright in the theatre.
