EOS R5 C "Gradient" look when using faster shutter speed

[RobinLewis]

Hey all, I have a tech help with my Canon R5C. I have written the tech info on the photos. However the one with the faster shutter speed has that "gradient" look while the one with the slower shutter speed don’t. The only filter I am using is a UV filer at the end of the lens. Any ideas in what could be going on?

Greetings,

What's your question? 🤔

Can you please elaborate or provide more information so we can understand what you're asking.  

I understand these are still images because the camera is not capable of shooting video at 1/8,000 of a second.  It appears that your shutter speed in photo 1 is too fast for the lighting conditions resulting in an underexposed photo.
