Nope. There is chip looking like PMU on board with at least two output power rails. For VoCore 1 there were two MT3410L converters, one for 3.3V and one for 1.8V. With switching converter total power consumption should be close to SoC power consumption, not depending on input voltage.

Also specification is pretty clear: 74mA wifi standby, 230mA wifi full speed, 5V input. Input voltage range: 3.6V ~ 6.0V.

It is a generalized statement. Very few SoCs have internal switch mode controllers. It is going to either be an LDO, or take a fixed operating voltage. Requirements for such will be specified in current, which is more useful than power.

Module level specs would be irrelevant in engineering because there is little incentive to use something like this, the radio isn't even certified. On that note, get your popcorn ready for when they ship to German backers and customs proceeds to trash them.

That's why PMUs are used. Just look at bottom side of the PCB - there are three coils, two of them very close to the chip looking pretty much like PMU.

No, read specification: 3.6 - 6V.
