A7rIV vs. A7rV File Size Increase - Reason?

DI_Jeff said:

Does anyone know why the RAW file size are larger on the A7rV vs. the A7rIV. It looks like they are roughy 5-10% larger in size for the same quality (uncompressed and compressed)?

I was surprised since they use the same sensor.

With compressed RAW I get about 300 less shots on a 128gb memory card.

Just wondering...

I wonder if that translates into better image quality? or low light noise performance. Just curious.

I sold my A7rIV so I can't compare.
