Recover photos from a broke iPhone 6

Is there a way to recover photos from an iPhone 6 that will not power up? I suspect that the answer is no, but I thought I'd ask the question to others in case there is a way. My iPhone 6, which has never been dropped or damaged in any way, simply stopped working. It won't power up, it won't charge, it's just dead. I purchased a new iPhone 7 and restored it using the last backup from the iPhone 6; however, the more recent photos were not on that last backup. If it is at all possible, I'd like to recover those additional photos from the phone.
