"PWM DC"? PWM by definition isn't DC. PWM generators even at maximum drive aren't 100% duty cycle (yes, effectively DC considering the response of the LED, but still not exactly DC).

Yes. PWM is a DC voltage with varying pulse widths. It never goes below 0V like AC.
BTW, Frank could have just used a transformer like <https://www.amazon.com/dp/B094NRRKC1> to simulate a 6VAC dynamo, or even a 16-24VAC doorbell transformer with some resistors to divide the voltage and limit the current, but it's really not worth spending much money to try to fix an inexpensive bicycle headlight.
