EOS 5D Mark IV Poor image quality

[billwestermeyer]

Please excuse the rather basic question. I recently purchased a refurbished 5D mark IV from Canon USA. It is replacing my 6D mark I. I've been very disappointed with the image quality I'm getting from the camera and figured it was just an amateur photographer trying to figure out a new camera. But it really doesn't seem right, and I'm hoping to get some advice. I've attached an image I captured with the 5D and a Canon 100mm macro IS USM. ISO 400, 1/500, F 10, and the camera is about 3 feet away from the butterfly. I saved the image as a JPEG, but it is an unedited raw image. It seems pretty grainy to me. Does it to you? Should I have Canon check it out?

thanks

Slightly off topic.  Is DPP and EOS utlity available for Android ?

No both of these apps are only available on Windows or Mac. 

There is a DPP express on iOS devices
