Lossy Compressed Raw Underwater - SONY A7RV

For those shooting the Sony A7R V underwater (or a similar Sony system), have you run into any issues using Lossy/Compressed RAW?

In particular, have you noticed banding, lines, posterization, or other artifacts in blue water backgrounds when editing files, especially after significant white balance or exposure adjustments? Or has it been a complete non-issue in real-world underwater use?

I'm asking mainly in the context of fast-action subjects such as the sardine run or Magdalena Bay, where shooting in Compressed RAW allows 10 fps, compared to 7 fps with Uncompressed or Lossless Compressed RAW.

I'd be interested to hear whether anyone has seen any image quality compromises underwater that would outweigh the benefit of the higher frame rate.
