Also explains why GM put that 1st-to-4th manual skip shift feature in some of its big V8 sports cars back in the day? (Hmmm... do they still?)

I wonder what we'd find if we looked at owner-reported fuel economy of manual vs. automatic transmissions for a non-hypermiler's type of car. How about, say, the Subaru/Toyota BRZ/82? My theory is the manuals will still be less bad / better than the automatics, relative to their respective EPA ratings. I may poke around Fuelly and see, just for fun.
Small sample size but if you look at Fuelly for 2019 Corolla Hatchbacks with the 2.0L

8 Automatics (CVT) averaging 36.0 mpg (EPA Combined = 36 mpg)
4 Manual (6-speed) averaging 34.1 mpg (EPA Combined = 31 mpg)

EDIT:
Looking at European Ratings the autos still beat the manuals on the WLTP cycle but they are a lot closer. From the UK site nextgreencar:
