The answer is from what I can tell...YES
I noticed some nice hubcaps on an XB (similar to mine) and I walked up to the car and
talked to the owner. On closer inspection I could tell that his tires also only have 4 lugnuts
but the hubcap had 5 and they were just decorative. When I pointed it out the owner got
notably upset, as he was not the person who put on those hubcaps, but he had a similar
situation in a previous car and had spent over $2k on an issue he could have resolved with
under $80. I purchased the style of hubcap mentioned in my question and they installed
very easily and look great.
