One of the cases of RAW processing that can be particularly annoying even to "normal", non-OCD photographers" is "Shading Comp.". Folks unaware of the issue had that enabled when shooting mountains in clear weather and came home with colored gradients in what should have been deep blue skies.
Interesting do we know if all Sony models are affected by this?

The Sony A7R V no longer exhibits the infamous "Star Eater" behavior seen in earlier models (such as the A7R II to IV). Even at exposure times longer than 4 seconds, there is no hidden noise reduction affecting the RAW files.

But it really doesn't matter anyway, nobody is looking at anyones photos for longer than 5 seconds and on a 6 inch screen too...
Sadly this is true, but I enjoy looking at my photos on larger displays

Yeah. That took years of petitions and moaning posts to be finally silently dropped from the firmware.
I really wish Sony would apply software fixes to all their current cameras. It seems like the Sony answer is to buy the next model to get the bug fixes or in some cases wait for the next model. For example, the a7rV came out over 2 years ago, at this point is it worth picking up or waiting for the next model to get the improvments.
