Anything listed as “DB Air IL” should all be new internals and fine.
If it’s the old model you’ll need to check if it’s had the upgrade/fix or not as there are a few old ones knocking about.
On CRC it’s listed as “DBInline” which is a bit ambiguous, could be the old model pre-fix despite the pic being of a DBAir IL so I’d be wary.
FWIW, I’d buy it from TF tuned for £15 more and have the piece of mind* that it’s definitely the right model and OK, and that if anything does go wrong with it you’ll probably have a better customer services experience with TF.

*cos they do this:
What we do to new shocks BEFORE you get them:
Strip, check for assembly faults, ensure optimum function
Set-up the shock for you, your bike and the way you ride
Supply correct mount kits so they’re ready to fit and ride on your bike
Detail the set-up we’ve done for you on the back of the invoice, for your future reference
