I've never damaged a LED by *trying* it on a non trailing edge dimmer.

then you've not used a CR PSU led light for that job.

How would I know a CR PSU from an LED that simply says 'dimmable' (with a
suitable dimmer) ?

Dimmable LEDs can not contain CR PSUs, they don't survive chopper dimming. The only way to tell a CR PSU LED from an SMPSU LED is to open it up.
