FRV's Highlights inspection is not about 'recoverable highligts' (reconstruction/simulation of missing details in some channel(s) based on channels with details) but about inspection without any extra assumptions.
It is just:
gamma change (so more contrast in highlights, by reducing contrast in shadows)
Optional exposure decrease
Optional UniWB white balance
We do not make any assumptions about the ability of the RAW converters to restore highlights.
It might be strange, but 'Overexposure display' can give a better estimation of recoverable highligts area:
If only a single channel is overexposed (usially the green one, so magenta overlay in Overexposure display)
And the overexposed area are near-neutral in color (clouds as a good example)
then this area is probably recoverable in HL reconstruction.
If overexposure detector shows completely black area (all channels are over-exposed) this means unrecoverable highlights.
