True Tone only adjusts the colors of your screen to make it more readable in certain environments. You would want Auto-Brightness turned off, you can do so in Settings > Accessibility > Display and Text Size > Auto Brightness. But something important to keep in mind, even if you've done all that, if your iPhone gets too hot it will as a safety measure automatically dim or blacken the display to protect the devices internals. This cannot be changed.
