This is only partially true. The problem with LED lights is that they deviate quite a bit from a Planck and/or daylight frequency curve. So you can end up with colors looking different even if the color chart looks right. And even the best Aari LED lights have ssi scores of only ~75. I wouldn't be surprised if this is a part of the effect the author describes.
if that was the case then teal/orange grades would be "impossible" as most lights don't kick out that much teal (~510nm) Not only that, but you can micro adjust the colour of these lights to suit your needs, which means you can have much richer colours on set and not worry about colour cast. if it was such a burden on the film maker, and limited artistic expression, then we'd see holdouts for tungsten lights (in film…
Although I guess it's their size that makes them stand out, maybe the LEDs I just don't notice.
