in premiere there is no acr, but(!) the cdng's with debiased and maximized valuerange are working with acr and other applications as well. the pink-highlight-fix is working (only with maximized-attribute!), but this is not a good idea if you're working with acr fi. Hope, adobe will do the update asap.
premiere does not read 14bit dng's (by now, and i think it won't in the next time) and looks awful with the canon-typical valuerange. AE is slow because its a compositing software with way more variables to define/create a picture.
