LOS ANGELES — It’s the most celebratory weekend in television, a time for red-carpet looks, thank-you speeches and lavish parties. But as the 71st Primetime Emmy Awards approached this week, Hollywood seemed glum.

The lack of enthusiasm comes at a time when billions of dollars are washing through the industry, thanks to the new demand created by Netflix, Amazon, Hulu and the streaming services to be unveiled by Apple, The Walt Disney Company, NBC Universal and Warner Media.

And there’s a wealth of buzzed-about shows that could be recognized at the Emmys ceremony on Sunday, including the popular “Game of Thrones,” the groundbreaking “Pose” and the critically adored “Fleabag.”
