I don’t think that this corresponds to the thing called “Frutiger Aero”.

The Windows Aero style existed in 2004, and somewhere around 2017, the style Frutiger Aero was invented, partly based on those styles but partly new.

Just like Vaporwave.

Some aesthetics existed in the past (like art deco), some are invented out of materials from the past (like art deco revival).
