Here is the Canon 50L at f1.2
Note the pink license plate behind the rear tire on the right.
There is some 'overcorrection' on the left side of the plate when using the pink CA removal slider in Lightroom.
The pink bicycle on the right of the frame is unaffected. Only a tiny amount of that plate matched the CA removals algorithm.
Anything less and I still had noticeable CA around the subjects plate.
I could go back and reprocess the original raw file, but I'm not too picky either.
As others have stated, applying the CA slider to the whole image can have adverse affects on everything that color in your image.
If you want to see it in action upload a google image of a pink flower and try out the slides yourself.
It clearly shows you how even a little 'correction' can wash out for whole image.
