So I feel like True Tone or something is still active even if we're turning it off. Last week I bought my 2nd iPhone because I wasn't happy with the warmth of my launch day one. I turn it on in my kitchen and it looked nice and cool when I turned TT off. As I'm setting it up in my bedroom waiting for apps to finish downloading, it starts to look warm to me. But in my mind, it still looks better than my first iPhone and now I figure my return period is extended by another week so I return my first iPhone.
Days to come I keep using it and just not happy with the warmth. This past Friday I bought another iPhone (not an exchange, bought another outright and kept my 2nd iPhone) but due to unrelated circumstances I just unboxed that iPhone today. I turn it on in my kitchen again and when I get to the part of setup to turn True Tone off it looked nice and cool! I was happy but then I noticed a "knick" in the display so I didn't bother continuing with setup and went to the Apple Store and exchanged it.
Just got home a little while ago, turn the new phone on (technically now my 4th) in the kitchen again and get to the setup part where I can compare True Tone on and off. Again, I'm happy because with it off the screen looks nice and cool!
Now I'm sitting in my bedroom with this latest iPhone and the more I look at the display while the apps are syncing up the more it looks warm to me again. I go into the settings to toggle True Tone on/off and the display does nothing! Literally no change! And I know it's functioning because in my kitchen I could see a very clear and distinct difference with it on vs. off.
So I grab my "older iPhone" (the second one) and perform the same test. In my kitchen TT on vs. off is a noticeable change. Take it into my bedroom, toggle it on and off and no change in the screen.
Has anyone else performed similar "tests" and seeing the same outcome? It's feeling more like software related than anything else. Don't get me wrong, some phones I've seen here are definitely piss yellow and that's a problem. None of the iPhones I had were that bad. Just warmer (with TrueTone "off") than my X was and my iPad Pro is.
