I think you're taking the responses incorrectly.
In a forum like this, I - and I hope it applies more broadly - are trying to share what we know and learn the most about our orchid culture so we can do a better job of doing so. If, in that process, we state something that is incorrect, we run the risk of it being "taken as gospel" and promulgated throughout the internet.
Myths like "
water causes root rot, "
plants don't use the green part of the light spectrum", and "
plants produce oxygen, but don't use it" fall in that category. By "flexing our intellectual muscles" and sharing the correct info when we have it, it helps people understand the truth.
As to the OP's query, the correlated color temperature may make a difference in the appearance of the plants, with the 5000°K looking bluer, but in the vast majority of "white" LED's, the 3000°K chips typically are more energy efficient, i.e., more photons out per watt consumed, and that could make a difference to some growers.
