I upgraded my 12.9 M4 to iPadOS 26, and was presented with this Lock Screen:
I don't know why it changed my lock screen wallpaper, or why it changed it to black and white, but this is not great for people with vision impairments. Heck, I have something like 20/13 vision and I still had trouble reading the keyboard. Hopefully throughout the beta process Apple corrects some of this new design.
Also, icons inside of folders are more difficult to make out as well.
