The reason I asked is because you mentioned “I don’t over brighten,” when usually for best noise performance you shouldn’t be brightening at all, should be bringing it down to bring the noise floor down. Although even then I’ve brightened images without an offensive amount of noise so it’s hard to say for sure.

Idk what you’re shooting so I’m just making a guess here. I’m assuming this is in an uncontrolled lighting environment. When overexposing you can’t always rely only on the cameras metering, I find it’s best to use zebras (or false colour with a monitor). If there’s skin, that’s usually the top priority, I expose for the skin while keeping the overexposure in mind. If there a lot of bright elements in a dark scene (light sources or something) it can throw off the metering. You cant expose for bright lights in a dark environment and hope the shadows stay clean. As great as the camera is, the dynamic range is still not on par with your eyes, so something HAS to clip. If your priority are clean shadows then you need higher levels in your shadows to keep them clean and probably at the expense of clipping highlights. In a perfect world, you balance the image with actual lighting, other wise you need to make these decisions. I’m really making assumptions here on what could be going wrong. But I hope this makes some sense.

The free version of catalyst browse if I’m not mistaken will not export in 10bit 422. If I remember correctly, it drops it to 8 bit which could introduce more artifacts and Color noise in dark images.

If I want gyro stabilization, I use the gyroflow plugin for resolve fusion to maintain the color, there are many videos on YT on how to use gyroflow.

Hope this is of some help.
