yeah, I know it mostly does require root. But on LG's UX you can uninstall some of the pre-installed apps without rooting(I have a LG G2 so I know that). There are some of sony's pre-installed apps like what's new, social-life, lifelog, movie creator, xperia lounge, and the playstation apps that I don't find useful so I wonder if you can disable or uninstall them. I haven't had a sony phone in years so I don't know.
