That makes sense and shouldn't have been that difficult anyway. For the barbie glitter scene there's obviously more chroma 'texture' to apply variable bitrates.

Flat colored scenes could continue using lower bitrates. Where more complex models could be useful is avoiding entropy coding of useless details etc (e.g. if those details were artifacts of processing in the first place).
