I always assumed that the main usage of Hybrid was to filter the source somehow and then convert it to whatever you need. 
Starting with H.264 encoding to 10bit (and thus adding a 8bit -> 10bit conversion) makes sense for compression, sadly 10bit H.264 didn't make it into the main profile and thus hardware vendors didn't support it, but starting with H.265 10bit is kind of mandatory.
Even encoding 8bit as 10bit makes sense to avoid introducing banding and gain a bit better compression.
(the better compression gain is less with newer formats, since the encoders internally usually use 16bit calculation precision anyway)
