Kinda, with the script. But not the lugs, or the markers, dot track, etc. Those IWCs are straight Patek imitations.
Anyway, Japanese watches of that era were obsessed with imitating Swiss watches (could argue GS still are), so, yeah, not an enormous amount of innovation, but it's about the execution and the small details. I do think those new Citizens are pretty clearly "inspired" by Grand Seiko product of the last decade or two if you look at the cases and dials.
The Hi-Line is extremely similar to the Seiko Lord Marvel though, as the Citizen Deluxe was to the Marvel. They came out practically in the same years though and I don't know enough about them to know which came first. They are very similar designs, down to the script on the Hi-Line looking super close to the Lord Marvel.
