Audiences expecting any surprises from former FBI director James Comey's sitdown with ABC News's George Stephanopoulous may have been left sorely disappointed.

After weeks of book excerpts and promotional clips, most of the biggest bombshells from the interview were already well known. But the smaller details from Comey's memoir, "A Higher Loyalty," that he divulged in the "20/20" special on Sunday night hold the most intrigue.

"What I think will make some ripples are the additional details that are provided in some of those anecdotes that he's telling," said Lachlan Markay, White House Correspondent at The Daily Beast.

Markay said that the most dramatic elements of the Comey-Trump saga are not grabbing the headlines because, "most of that has leaked out over the past year or so."

Comey spent most of his primetime interview and much of his book recounting the early days of the Trump administration, and the events that would ultimately lead to his termination. Those events have been well documented by Comey and the news media, but that doesn't mean the book won't make news.

In fact, more tangential stories like Comey's revelation that the White House chief of staff John Kelly called the president's firing of Comey "dishonorable" could have "the potential to actually affect some staffing decisions and policies," said Markay.

The Hollywood Reporter said the early ratings numbers for the "20/20" special show the Comey interview drew an average of 9.8 million viewers for ABC. One of those viewers may well have been President Trump.

"The president of the United States is watching this and has been watching the Comey media blitz very closely," said Asawin Suebsaeng, White House Reporter at The Daily Beast.

Comey is set to appear this week on "The View," "The Late Show with Stephen Colbert," and "The Rachel Maddow Show."

"A Higher Loyalty: Truth, Lies, and Leadership" hits bookstore shelves on Tuesday.
