WEST HOLLYWOOD — HBO said a final goodbye on Sunday night to two of its biggest hits: “Game of Thrones,” which has a won a record number of Emmys, and “Veep,” which starred Julia Louis-Dreyfus, a six-time winner for best actress in a comedy.

But if there were concerns that this would be HBO’s last big night in a while, there were no signs of it at its Emmys after-party. Held at the Pacific Design Center, the shindig was a thumping victory lap for its stars, show runners and producers, and their haul of gold statues.
