Are both those Legendary or can you even get up to Legendary without the skill boost?
Oh, yeah, sorry: in both of those scenarios the armor is Legendary.

I was also confused by the "Legendary" tag at first and I'm not sure why there isn't a hard cap on armor improvement. Maybe in expansions we'll need to go beyond the overall rating of 567.

Now that I think about it: I did get past the armor cap without Fortify Heavy Armor enchants because I was also carrying a Legendary Blades Shield.
