Better (or simply more) ARM processors, no matter who makes them, are a win. They tend to be far more power-efficient, and with performance-per-watt improving each generation, pushing for wider ARM adoption is a practical step toward lowering overall energy consumption.

Are ARM processors inherently power efficient? I doubt.

Performance per watt is increasing due to the lithography.

Also, Devon’s paradox.

Aside from lithography there's clever design. I don't think you can quantify that but it's not nothing.

Actually power efficiency was a side effect of having a straightforward design in the first ARM processor. The BBC needed a cheap (but powerful) processor for the Acort computer and a RISC chip was When ARM started testing their processor, they found out it draw very little power...

... the rest is history.

You're getting your history mixed up.

Acorn won the bid to make the original BBC home computer, with a 6502-based design.

Acorn later designed their own 32-bit chip, the ARM, to try to leapfrog their competitors who were moving to the 68000 or 386, and later spun off ARM as a separate company.
