I highly doubt anything was lost.
Who is buying this? RE fans. This isn't going to set the world on fire, even if they re-rendered all of the backgrounds and remade the animations for 60fps.
Would have made a difference to the reception in this thread (and likely others) from the same core crowd who will be buying the game, and feeling let down that Capcom didn't do a better job on the overall quality, specifically the background IQ. It's pretty clear given a choice that everyone would prefer native-res backgrounds.
If you believe the original background files weren't lost then you can understand why people would be upset that they didn't bother improving the backgrounds, which would have satisfied everyone and been a better port.
