How to tell a UK DR900X vs a DR900X Plus

[skoof]

Hey all. Been looking at refurbed DR900X 2ch cams on Blackvue's UK site and was curious whether it was the '900X' or '900X Plus' they're selling. Called them and was told they don't distinguish between the two so I've no idea what I'd actually be ordering. Given the differences in sample image/footage quality between the two I'm not comfortable ordering on the off chance I get lucky and receive a unit with the upgraded processor.

Any idea how I find out which version they're actually selling? Or is even worth worrying about in terms of real-world day-to-day use?
Thanks

In answer to my own question: I took a punt and ordered the certified refurb 'DR900X-2CH' from Blackvue's UK distributor. While the box was marked 'DR900X-2CH', the camera inside is marked as a 'DR900X-2CH Plus', as is the user manual, so all good on that front.
