When dimming tungsten lamps, it was pretty well known the efficiency
dropped dramatically. In other words, you got less lumens (or whatever)
per watt consumed. Does the same apply to LEDs? Or just to a lesser extent?

no, LED efficacy improves a bit when dimmed as V_f drops a little.


Normally only true from the 80 to 100 % dimming range.
