It was never in their official specs so you have to look for reports
from people who've tried it. I'm pretty sure both current internal Blu-Ray models WH14NS40 and WH16NS60 will read and write CD-R99, but couldn't tell you anything about if their slimline external models can do the same--those are made from laptop drives, probably from a different engineering team. But with how easy it is to return things nowadays... well you could just try it.
Note that CD-R99 also requires a compatible
player to read back the whole disc, + your car or Toshiba-Samsung (TSST) burner may not cut it, and either just stop reading at the CD-R80 standard 700MB or even be unable to read the disc at all because the tracks are too close together.
