CRI Issues are severe (check more info at http://www.personal-view.com/faqs/laboratory/measuring-lights-faq#color-rendering-index )

Actually, they are so severe that every time you measure CRI for LED light and base your opinion on it… God kills a kitten.

And in 2016 work on new standards is very active.

And things now becoming more complex (but lot more useful):

Global Lighting Association – which represents 5,000 lighting equipment makers – did not like TM-30 and said it would support an additional colour quality metric, such as one based on colour saturation, ‘that represents a significant and meaningful improvement’ but only in conjunction with – rather than a replacement for - the existing CRI system. The organisation also opposed to the establishment of regulatory or other minimum performance requirements for a colour rendering index of greater than 80 for indoor lighting applications.

Of course, as you can't optimize for 99 samples arranged this way, you also do not want to be forced to use higher cost leds meaning that your profits will fall. It is much more easy to make something for your business goals.
