There’s a lot of rubbish some people talk about 12 vs 14 bit RAW files. The fact is, by the time you get to about 800 ISO even the best FF cameras only have about 10 bits worth of dynamic range (at the pixel level) so 12 bits are ample as the bottom 2 will just be noise anyway. It will only be at very low ISOs where you might see some difference, and then only if the sensor has low read noise. Of course you get a bit more back when downsizing, but RAW files contain per-pixel data.
On an ISO-invariant sensor you lose one bit of resolution for every doubling of ISO speed anyway, so even 12 bits becomes irrelevant. Of course this camera is clearly not ISO invariant as it’s probably optimised for higher ISOs needed for action photography (the Canon & Nikon equivalents to the same), so it might be that the loss of (bit) resolution doesn’t follow that precise model, but it’s true in general.
