I’ve found success using Blu-Ray Dot Com’s sale filtering tool:How do I find a film with DTS:X soundtrack? I feel I should have one to test my AVR's handling of the format, but in the UK I'm struggling to find one. Search Amazon UK for DTS:X is a dead loss, as is searching the DVD Compare site.

That should give you a result of current on sale DTS:X titles. I’ve found that it’s *mostly* Universal films that have it. I have: Casino, Blues Brothers, The Thing, Edgar Wrights Cornetto Trilogy (Shawn of the Dead, Hot Fuzz, The Worlds End), Puss In Boots 1, etc.
That being said, when those titles get picked up by other distributors, it seems like it’s converted to Atmos. Puss In Boots for example has an Atmos track via iTunes Rental, Waterworld got ported to Atmos for the fancier Arrow Video release, etc.
I also note that the official page for Pure Audio Blu Ray, of which most Atmos disc releases use does have the DTS:X logo on their site, so there’s a possibility there’s at least one music only DTS:X disc out there, but I can’t seem to find it.
