Photos of new or very lightly used HVSS rubber tires show a casting seam. Photos of HVSS rubber tires after a few miles show no casting seam.
Photos of most VVS roadwheels show no casting seam. Perhaps the photo by jester75 shows a new or lightly used one (the other three visible roadwheels show no seam).
To the OP, the vast vast vast majority of VVS roadwheel pictures show no casting seam. You decide what you want. Perhaps a seam was normal in the production and present on newly mounted ones. This is one detail I'd NOT keep on either VVS or HVSS roadwheels persnonally.
