It's not that they're non-canon, but it is more evidence that any involvement from Kish/his team is limited at best. There are a number of occasions where the digital comics use the anime colourings when Kishi's team have not released any. For example, the second mizukage was never coloured by Kishi's team in the manga, so the Shueisha team went for the only available colourings, the anime.

They're official, and useful in many cases. But in terms of the colours used, they should be treated just as the anime is. If they colour something before Kishi's team does, then we have to be aware that it may not end up being 100% accurate.
