Whilst normally I'd completely agree that such concerns are not really that relevant, in the Mac version of the Canon plugin there is a similar 64 bit limitation.

This means that in 64 bit I only get perceptual, sat or rel col with no BPC available.

The option of BPC can be quite handy :-)

Depending on the profiles I'm using and what software made them, I can see noticeable difference in -some- images between the options.

I'll admit that it's not much, but it would be nice if Adobe did get round to making the external CMM run OK at 64 bit (Mac and Win)
