This might be related to the fact that ‘lspci –v’ the values which the OS has seen and configured, and ‘lspci –x’ shows the actual values which resides now in the values.

Lspci -v and -x show different values for various PCI BARs in my system. It appears that reading 'resource' and 'config' from sysfs in dom0 yields the differing data. The 'config' data matches what is actually programmed into the BARs. Why are these different?
