Narrative:

We filed and were cleared via the VKTRY2 arrival leaving ZZZ. On descent to dfw we were cleared to descend via the JOVEM4. Not realizing that was a clearance revision we started down flying the VKTRY2. There was no revised clearance or route change transmission; just descend via the JOVEM4. The waypoints are the same for the 2 different arrivals with different crossing altitudes. As the pilot monitoring I should have checked the route page to confirm that was the arrival in the box. An alert from ATC that JOVEM4 was a revised clearance would have been nice. We did not realize we were given a revised clearance/reroute.if the arrivals had different waypoint names; that would help alert crews because we would not see those points on our legs page indicating we have a different arrival. Dfw had been in a north flow all day and we should have filed for that. ATC alerted us we were 4000 ft low approaching letnn. We were on the vktry 2 vertical path.
