First time poster here, I thought I'd make an account and share my thoughts.
Upgraded from 15 Pro (non-Max) to 16 Pro (non-Max).
When I was setting up the 16 Pro, I immediately noticed that the screen had an obvious yellow tint compared to the 15 Pro.
So I compared them side-by-side with the same identical settings (max brightness, both TrueTone on vs off, set white point off, auto-brightness off) and it was quite clear that the 16 Pro had a yellow tint compared to the 15 Pro. At the time, I did not notice a significant difference in subjective screen brightness.
I've been using the 16 Pro for a few days now. While I do not bring my older 15 Pro everywhere with me, when I look at the 16 Pro under the usual lighting conditions that I experience (walking to and from work, fluorescent light at work, etc), I do think the 16 Pro is much more yellow than the 15 Pro (without comparing them side by side).
I was excited to discover this thread and thought to post some photos to compare them side-by-side.
Please find them below.
Both top and bottom photos were taken in RAW, same manual exposure settings, opened in ACR and directly converted to JPEGs without any custom post-processing.
To my surprise, there is no longer a marked difference in screen color temp between the 16 and 15 Pros.
The photos were taken with both phones at max screen brightness (I'm aware 25% brightness may not equal 25% brightness on the other phone).
Both phones were subjectively cool to the touch.
Auto-brightness was turned off for the test, but when turned on, the results are essentially the same relatively speaking.
No screen protectors/privacy screens on either phone.
In both the TT on vs TT off tests, the 16 Pro does look slightly more yellow.
But if anything, the 16 Pro is slightly brighter subjectively.
I also compared my 16 Pro with both a 16 Pro and 16 Pro Max display models.
Mine is essentially the same brightness and tint as the display models (again equalizing variables: auto brightness, max brightness, etc).
With TT turned on, I thought both my 16 Pro and the display models looked much too yellow under the Apple Store lighting.
