Sony A7III posterization banding - blue skies

Recently I've noticed that many shots taken with my A7III (particularly using the 16-35 F4) contain very severe posterization banding in the sky. I'm shooting with silent shutter disabled, and to uncompressed raw files - the effect is clearly visible in both the raw files and the JPEGs. I initially noticed it in a shot that was underexposed by about a stop, but it's also visible in my daytime shots that are correctly exposed (although less obvious).

Has anybody else seen this? Any help would be much appreciated.

Here's a sample -  uncompressed raw files present the same issues. Note the concentric circles in the sky.
