I'm not sure if this is the norm in Europe, the only chain store I know that sells high CRI (>90) bulbs is IKEA. If I go to my local home store or supermarket, they are all junk Chinese bulbs that I doubt are really even 80 CRI.

CRI isn't even something you can filter by on their online catalogues. At least the new EU energy labeling let's you see what the specs are.

Cheap bulbs do a lot of "CRI hacking":

It's easy to make a bulb that scores higher than 80 - still, they usually have poor R9 (red reference light source) scores, which is noticeable.
