It's mostly about auto white balance performance yes, but it's not just about white balance, even when set with grey card almost all my canon cameras had troubles with highly saturated reds.of course with raw converters you correct a lot of flaws but better have it straight from the beginnning.
It's not a biggy if you are a landscape shooter and have few pictures at the end of the day, However when you cover an event and you have to hand 500+ pictures next day, it's a true nightmare
Time for you to read up on Canon AWB settings for the latest cameras.
Hi toni
sometime I'm surprised from your questions. I know you well. You are telented photographer , times ago I have learned from you photography - 14..16years ago. At that time you organized photo parties - Marcus and Klaus ware active too, the new internet stars Brightcolors and JJ_so ware with zero posts here.
Taking a good exposure and getting the right WB is something basics, and I cannot imagine that you did not know it
I think such charts are misleading. Just like during the film era you won't use the same color profile for every scene.
e.g. for outdoors I used Velvia, maybe Kodachrome. For portraits there was Fuji Astia. For street photography, Provia was good.

Exactly that's why I was questioning if such test results were relevant in our daily practice
It's extremely hard to tell really.
For me, Olympus colors feel fairly off for instance. Now the big question is ... is that the RAW converter profile, the WB or ... me. ;-)
I'd still put it on the WB.

Newer Canon bodies have an extra choice setting for WB, the traditional "keep some of the warmth/character of the light conditions" Canon look, and a new more "neutral" one. That is what has changed.
