Developers are paid to lie, it's their job. CDPR are just calling it "optimization" instead of downgrade. Just because you change the word doesn't mean you changed what you did, it still looks a lot worse than the e3 trailer.
They will also toss around stuff like "The e3 trailer wasn't a finished product you can't downgrade something that never got released" and "That was running on an old engine, the new engine works and looks a lot better".
CDPR should just outright say it's a downgrade because they couldn't get it to run on consoles and they didn't want to spend extra time making it look good on PC because then it wouldn't sell on consoles. If they didn't lie it'd be more alright.
EDIT: Holy shit I watched the video after I posted and the guy said exactly what I posted. That's beautiful.
