Easy way to tell... if the aircraft has Global First, it's the old 67I with the rather dated Y product. If no GF (only BF in a 2-1-2 configuration) then it's the newer 76E with AVOD/power nose-to-tail and larger bins throughout.
The first 67I (N661UA, nose 6461, to become 6661) is presently in the shop for conversion to 76E, a process that will take approximately 90 days per ship. It may accelerate toward the end of the run. Thus, there are 20 67I remaining in service.

And as noted, the Y seat comfort on the 76's is the best on all of UA's long haul birds. I wouldn't worry.
AVOD is audio/video on demand, and only the 14 reconfigured 76E ships have it nose-to-tail. The three-cabin 67I have AVOD in premium cabins only, and all but three have streaming AVOD/wifi. All 67I are looped-video only in Economy.
