Different Colors on MacBooks

[liveryko]

Hello,

I have 2 Macs, one Macbook Pro 15 with i9 and one Macbook Air M1, and when i apply a LUT or try to do color correction on the Macbook Pro 15 on a VLOG video file from a GH5 it creates some kind of banding but the same exact project on the Macbook Air look good with barely no banding...

Here are some printscreens of the issue:

The files from the GH5 are MP4, VLOG, 420, 8bits, 100Mbps and LongGOP.

I tested on other Macbook Pro 15 from the same year and on an iMac 27 and they all do this "banding".

Does anyone know how to solve this issue?
