Hey there TADesigns,
This could be related to the brightness or display settings, other than Dark Mode. Use the guidance in this link to help with your display. Make sure to check Night Shift settings, True Tone, and double check for a schedule or any other settings for Dark Mode: Adjust the screen brightness and color on iPhone - Apple Support
Also, take a look at the steps below to check if there are any additional settings affecting the color and brightness:
If you have color blindness or other vision challenges, you can use Color Filters to help you differentiate between colors. Color Filters can change the look of things, like pictures and movies, so you might want to use it only when needed.
Open the Settings app, then tap Accessibility > Display & Text Size > Color Filters. You'll see three examples of color spaces to help you select an option that fits your needs. Swipe left or right on the examples to find a filter that works best for you.
Choose a filter
When you turn on Color Filters, you can choose from four preset filters:
• Grayscale
• Red/Green for Protanopia
• Green/Red for Deuteranopia
• Blue/Yellow for Tritanopia
Adjust color intensity
You can adjust the intensity of any of the Color Filters to fit your needs. Use the Intensity slider to customize a filter that's more intense or less intense.
Adjust Color Tint
If you have color or light sensitivity, tap Color Tint to change the hue of the entire display on your iPhone, iPad, or iPod touch. Use the sliders to adjust your display's hue and the intensity of the effect.
More display accommodations
You can also find these accommodations on the Display & Text Size screen:
• Bold Text: Makes text bold.
• Larger Text: Tap this, then turn on Larger Accessibility Sizes. Use the slider to choose your preferred reading size.
• Button Shapes: Adds shapes to buttons—for example, an underline beneath Back buttons.
• On/Off Labels: Adds On/Off labels on preference screens.
