As far as I can tell after just looking at the specs, what I said is still the same. For example, an Intel Core Ultra 5 Processor 338H has a TDP of 25-65W vs. the M5 TDP of 3-27W. These aren't even directly comparable, but it gets worse going higher in the Intel Stack.
Further, every Windows laptop seems to have a worse display. For example, an M5 Macbook Pro 14" has a 120Hz 254ppi mini-LED display with a peak brightness of 1600 nits vs. a Dell XPS 14" with a 120Hz 161ppi LCD display with a peak brightness of 500 nits.
So it seems like they have figured out that they can put bigger batteries, worse displays, and throttle TDP to get better battery life, but it is still not possible for them to beat Apple's efficiency just based on those TDP numbers alone—these chips are just drawing more than 2x the power at peak load.
I don't understand why there isn't more effort towards ARM in the Windows world.
