Yes. It will be more vivid and will look how it’s supposed to be calibrated from factory. The reason why some people prefer True Tone because it changes the screen tone to be warmer (less blue) which is much easier to the eye when using the phone and especially reading. However, this will also make the phone look more yellow and not as vivid when on. True Tone is actually a very good feature. When indoors the tone will shift more towards the warm side depending on the lighting, but outdoors where it’s bright, it will shift more toward the cooler side. I will eventually use it at some point if Apple decrease the intensity of warmth tone indoors.
