I just noticed that the update for Spyder2Express software changes the
only available target for LCD to 6500K.

Why would you do that? Native white point target for LCDs was
considered to be one of the advantages of Spyder2Express over the i1 LT.

If there was some pressure on Colorvision (from whoever was
complaining) to include 6500K and D65 you could make all of them
available. It wouldn't cost you anything and make your product more
competitive.
