Exchange

I bought the iphone 11 pro max a few days ago. At the store, no phones were on display because of looting, so i was not actually able to get a visual of the options. I didn’t actually see the phone until i got home to set it up to program. I wanted the 11 pro, but i was told it was small. Coming from the 8, i didn’t want another small phone, so i ended up getting the max. This phone though, is huge. I saw the iphone 11 pro actually with my own eyes, and it’s not as small as the worker made it seem. So since it’s only been 3 days since i bought the phone, is there any way to exchange it for the 11 pro?
