If it was actually cold stored it will likely work fine but perhaps with some fog. I've gone through hundreds of rolls of c200 and superia 200 that were cold stored and expired by 8-10 years. Results were good, but like I said, with significant fog. It didn't seem to affect color rendition significantly though.
I've been shooting expired but stored in my freezer C200 for years now. Zero issues.
Thing is, it WAS cold stored. By me. Not by a seller who may or may not throw that line in there for the sale. Or had it only cold stored for a week or so just before selling it..
