Minor update, the warehouse was sold out of the SE and the display was removed (I thought they had a lot, because they had many cards), though the online site likely still has them.
The wireless kiosk had a Pixel 3 there so I compared it. Granted, it was probably suffering from severe burn-in from being in demo mode for who knows how long, but the whites were much warmer than the new device. The panels in the 3 are from LG. The burnt in screen did look a more comfortable as it was warmer. For colour calibration, Samsung's own devices are probably better because they have a SRGB setting.
Pie does not have slider controls to adjust hue or saturation. iOS does.
Getting more used to the size, but finding other more noticeable issues, like Chrome not sizing to fit some (not all) webpages properly, etc.
Not loving the mix of pwm with pentile and odd (to me) colour calibration.
