Canon ColorData5: for ColorDataVersion=-3, SpecularWhiteLevel is most likely at `662`

[LebedevRI]

Note: i'm also not sure if 264 actually contains the PerChannelBlackLevel[4] or AverageBlackLevel[4],
but it seems there's some other blackLevel[4] at 703, but there's certainly no black levels at 333 index.

And footnote: said ver=-3 happens also for a lot of PowerShots:

Thanks. I'll add your SpecularWhiteLevel to the next release (12.71)
