17.41 update wrecked color on videos, photos, apps

woke up to find my iphone 10x+ updated overnight. Now my photos and YouTube video are all negative. The background to my twitter app is black background with white text —unreadable to me - need it to be white background and black text. I can’t recognize people or objects in my photos, videos are unwatchable, and my eyes need a white background with white text.

i changed the wallpaper so that my emails are white with black. I went to display and brightness and made adjustments. I went to accessibility and played with display and text size. Nothing works.

Help.
