It would be an interesting napkin problem to do. Yes it's relatively trivial, but multiply it by 1B smartphones running for many hours every day and how many cities worth of power are you wasting on extraneous shader cycles?
It’s still very little energy. Probably way way less than a bedside lamp per phone.
Phones aren’t a good place to try to save aggregate energy use at a population level. They already use vanishingly small amounts of energy compared to just about anything in your house.
