More or less, yep.

Read errors can be somewhat recoverable, if you write to that sector it
will remap if it can.

But anyway yeah, it's not an xfs I/O error, it's a disk IO error, and
xfs is bringing you the bad news.

repair may not have seen it because repair only looks at metadata, bad
sectors may be data in blocks, found when you try to copy data around.
