I thought I would jump in to this discussion about the S24 Ultra screen colours, I agree with the fact that vivid vs natural settings don't seem to show much difference, easier to see the difference if your phone is not in dark mode. I pulled up the same image on my S24 Ultra on the left and on my iPhone 15 Pro Max on the right.
I put both screens at 50% brightness and I ensured that true tone was switched off on the iphone and any adaptive colour tone or eye comfort modes and any adaptive brightness settings to make it fair.
The first thing I notice is how much whiter the whites are on the S24 ultra, the iphone has a yellowish tinge to the whites. Secondly the grey is much more accurate on the S24 ultra (I checked this same image on my professional colour graded editing monitor). The colours are more crisp on the S24 Ultra and sharper but certainly in no way are they muted compared to the iphone 15 Pro Max. As a professional photographer and videographer I would definitely take the S24 Ultra screen over the iphone especially when it comes to colour accuracy.
What do you think? Let me know in the comments below, before anyone asks I purchased both phones myself, no biases or review units here.
