Quite possibly white ones do. But thenso do fluorescent lamps which

But having used white LEDs to make a stroboscope flashing 100 or 120
times a second, I will assure you there's enough change in intensity
between 'on' and 'off'' to give a very clear pattern of the strobe
markings even with normal room illumination also on.

The old common standard for a mains stroboscope
was a neon bulb (+resistor).
They are still widely available, simple and inexpensive.
No, they are not very bright and need some shading or otherwise reduced ambient light,
but for a tool of infrequent use...
If it works why change it?
Don't modern leds use a still glow after being turned off?
