I haven't seen any data on it, but that's my understanding as well. (>1x is rare in today's market). But the NYT article does mention Honest Co. with a 2x on $1.7bn valuation, so there's at least that anecdote.
Then again, I don't know how transparent the financing is for these enormous companies, so maybe it is a bigger deal than I think. (I also don't lose too much sleep over it.)
