MacBook Pro 2020 display issue
I have a problem with my MacBook Pro M1 very similar to this one linked below -

To me it looks like a limited number of colours are showing, iCloud photos look terrible. I have tried the recalibration and even completed re-installed OS Sequoia 15.2 but the picture is still poor. All default settings used after reinstall. There is no flickering, no noise or other issues, it just looks washed out. The MacBook has had limited use and has no damage.
I had been away for a couple of months and when I returned I immediately updated MacOS so I am not sure if 15.2 update caused the problem.
