Are you downloading and opening in Illustrator?
I have downloaded the same image on my end and I agree that the quality of the file appears different than the picture in the preview. I will be reporting the same image to the Stock team.
Also, I am adding an image credit to your account so that you can license a different image instead.
Hope that helps!
Feel free to update this thread in case of any additional questions.
Stock team will follow up on the subject content ID issue.
Please try the same file in a few days ~ 11/17. File owner will make the fix.
