When you click the battery icon in the macOS menu bar you can see which apps are using significant energy, and in the 'Activity Monitor' tool you can also sort by energy usage.
I would be surprised if a typical ImGui app shows up there though (unless your renderer isn't vsync-throttled), on my laptop it's usually Chrome which is at the top of the list.
You can also write ImGui applications so that they only 'wake up' on user input.
