No. One looks like an xs:date. The other is indicated to be an xs:date
by some schema. However that does not make it an xs:date. It merely
means one process using that schema chooses to see it that way. Other
processes may use different schemas (or no schema at all) and see it a
different way.

And if you have a second process that compares them as strings? or as
dates in a different calendar? What then?
