Finally the YPbPr color scheme is not an M1 only bug. My U2414H has been running in the scheme for years in HDMI. When put in DisplayPort to Mini-DP it works fine in RGB. Couldn’t tell the difference between both scheme. I could patch it in HDMI since I’m still on my Late-2013 MBP15.
After a lot of reading, the problem seems generalized to Dell with Mac. But is it because only Dell shows the input color scheme in its OSD ? Nobody knows for sure. It’s very strange.
