A Z170 Extreme6+ With a Z170 Extreme 4 Bios

Was helping a bud troubleshoot a non-booting problem on a new build. Got that squared away, but...when he made it into the eufi bios screen it showed as Z170 Extreme 4 P2.40 .
So...he does the internet auto update (thinking it would flash the newest correct version) and it now shows as Z170 Extreme 4 P3.20
Head over to Asrock and d/l the newest Extreme 6+ bios and try to flash via instant flash....doesn't see this bios image at all.
Ever see or hear of anything like this?

The board came new with the Z170 Extreme4 P2.40 bios loaded on both the A Bios and B Bios.  The stickers on the bios chips do indicate that as well.  Doing an instant flash with the latest Extreme6+ bios resulted in "No Image File Found".  Multiple attempts using multiple USB ports, multiple USB drives, and using the F6 for Instant Flash and F2 through BIOS and selecting Instant Flash were made, all with the same result.

A google search shows the Extreme4 to be visually different from the Extreme6+, enough to the point that I'd be surprised if it was a Extreme4 board that with the wrong silk screen.

It's definitely the Extreme 6+ not an Extreme 4 mislabeled so it must have been fitted with the wrong BIOS. In your pics there appears to be a sticker over the screen printed text for the model but I suspect it probably says Extreme 6 as they are both based on the same PCB. The fact that it has the sticker though leads me to believe it is an early production model (old stock).
