Not seeing it. After I got the M1 Max 16 and updated Premiere to 2022 I tested by opening projects from the last month and compared output.
My main problem with Premiere 2022 was that they changed Lumetri's engine so all the videos were blown out with incorrect colour matching, so I had to regrade my projects. After I finished the regrade I exported them and they all looked the same as ever with high detail and no artefacts.
I also downloading some 4K and 8K log footage from the link below to benchmark the machine and test the quality of the output, which was all excellent.
On this page you will find downloadable Kinefinity MAVO Edge 8k Log footage, a few in 8K but most of them in 4K oversampled from the full frame 8K image, recorded in ProRes 444.
