What happens when you close your MacBook Pro lid? Various questions

I’m not an expert either, but I’ve experimented with closing the lid on my M1 Max MBP running Monterey and found that it enters clamshell mode [1] when I close the lid if my external display is connected via a USB-C to DisplayPort cable, even if no external (Bluetooth) mouse or keyboard are active. The MBP’s integrated keyboard and tracking pad are active, but when the lid is closed they are not accessible, so there’s no reason for them to inhibit clamshell mode.

Just out of curiosity (don’t want to digress) - how’s the light leakage from your new MBP? (See New MBP M1 Pro keyboard backlighting - uneven light leakage under keys?).

My guess about the turning a bit “blue-ish” might be because when the lid is closed, True Tone shades which are borrowed from the main display become inactive. It looks more “blue-ish” when you toggle off True Tone as well. I do that on my iPhone X because True Tone looks dull and faded to me there. But it seems easier on the eye on my MBP.
