From what I have read, the product is still in its infancy and does not have the smarts to adapt to every viewing environment. It actually just uses built in profiles and hopes to come close …
Problem is … what the device does cannot be measured by instruments in a persons home. The human eye can get fooled … but the instruments quite often don’t. Especially considering that the eyes see the whole environment while the instrument only sees a much smaller slice.
Some things we already know about brighter rooms … harder to see shadow detail (so we boost the brightness control) and it shrinks the color palette (so we need to go with a larger color triangle to compensate.) How much the triangle gets shrunk depends on the room …
