The flash is (no spiff used) only read once during boot and the "sketch" transfered into program memory in esp8266 for execution.

That is not true !
Only small pieces of sketch are transferred into RAM at a time.
This means that caching mechanism will transfer other pieces of sketch later during execution.

oh, I see, then I withdraw my statement about the flash power consumption.
But still I think that most of the 15mA are consumed by the esp8266 ...
