Recover data

So I had the iPhone 6s before upgrading to the iPhone 14 plus way back when it came out. The reason I had to upgrade was bc my data got deleted due to lack of memory space and I was devastated. I was told nothing could be done and I needed to upgrade and turn in the old phone as it bricked. I want to know if that data can be recovered without it having been backed up to icloud. I have all the phones info and would really like the pics and vids of my dead dogs back. Please, if anyone can help that would be amazing
