The fake wood is the SAME on all the interiors it is offered on...Cashmere/Ebony, Titanium, and Ebony, it's all the same wood. If anything, there's an optical illusion due to the different interior coloring that is throwing off your perspective.
The only difference in wood is GMC vs. Chevy, with the GMC's, being made slightly lighter and with a different fake grain. There's no specified color, model, grain, etc. just is what it is, via part number.
That said, you basically just need the wood pieces in general from ANY '07-08 Tahoe interior. It's just a matter of finding all the part numbers and ordering the right pieces, to replace all your silver stuff--the silver, by the way, being what a lot of people want INSTEAD of the wood. So there's even also the possibility of trading with someone locally.
Here's a good place to start as far as identifying individual pieces (well, without part #'s until they're ordered, etc.):

OR, you can go aftermarket and use a quality kit that essentially covers your current silver trim with a wood of your choice, edge to edge. Like this:

I've seen a few of the latter, and they're almost indistinguishable from the original wood trim, when done correctly...but are over top what's there, not a replacement.
