Did you even use that look-up yourself?
The first two reports hit claim 65% and 67% of the US market.
The topic here is the German market.

Since you didn't read the reports that your look-up referenced, you most likely didn't read to the bottom of the one I provided.
That is where the report describes how the Amazon e-book market share is being over estimated.
With that information, you can adjust that 65..67% yourself.

"Majority US market share of e-book sales" == yes
"Hugely dominate (of sales, publication, anything you care to name)" == no
