The problem is only being able to view the demo models in a shop under bright lights, you can't really see much about the quality of the light, just that it's there.
I don't think you were wrong to dismiss it for the reasons you did, just that there are other more subtle factors that play into it as well which change the field a bit.
Color temperature seems to play into circadian rhythms as well in weird ways, where whites closer to daylight will screw up a sleep cycle more than warmer whites. Even though our brain does interesting stuff in the visual cortex, there are other side channels for light to affect us via the retinal pathways that aren't associated with vision. Interesting stuff, and a decent amount of research in how light affects us and environment at night these days.
