In other words, you could feed an HLG signal to a dumb SDR display and the luminance would look mostly correct.

Interestingly enough, I do it the other way around:
Watching most SDR content with HLG.
This works quite well for most movie-like content
and b0rks most of the time with video-like content.
It seems that gradual luminance saturation (and chrominance desaturation) of the SDR film-curve in bright areas of the image fits the HLG-curve quite well.
On the other hand SDR with video-content peaking colors will look terrible with HLG applied.
My Sony OLED-TV allows to force the use of HLG on any type of input signal.
