Here's a pic of me in Propper 65/35 Ripstop Multicam.
It is genuine Crye, but is very much toward the dull green/ tan side.
In this pic you can see the difference between the fake (tan/ brownish) chest rig and my ACUs.
Here is another one which illustrates why it doesn't really matter.
The thing about Multicam is that subtle differences between fabrics don't really matter.
That is, to the Human eye they don't.
A (digital) camera lens will pick up a lot of details and differences that our brains won't recognize, and at the same time is more limited with regards to it's capture of colour and hue gradients.
If you want to buy into it, I'd suggest that you resist the urge to determine what the 'best' is... all licensed Crye stuff looks good. Find some ACUs that suit your needs and fit your budget.
Next, for all of your other gear, go out and look at it in person before buying. Bring a small matching item (like a garrison cap) with you to compare colour if you're worried.
Finally, don't worry about exact matching. Multicam confuses the shit out of the Human Brain, so you can get away with a lot of variation in person that you can't on camera.
Sometimes you can get a great deal on fakes which are indistinguishable, like my helmet cover, and sometimes something is 'good enough until you get something better' like my chest rig.
Then you get unavoidable differences like my Hydration Thing which is a licensed Condor product and yet doesn't match the rest of my gear side-by-side.
Keep an open wallet and a laissez faire attitude about this stuff or the +20% markup over other camo products will bleed you.
