Contrast: The electron gun can turn off (OLEDs as well btw), LCDs will always bleed some backlight (although they have region dimming now).
Color depth: only limited by GPU's RAMDAC, 10 bits were available in some Matrox cards.
Most of the negatives listed on the LCD side have been non-issues for years (e.g. viewing angles).
I own a 10-bit 4K Innolux VA panel from 2013 that washes out with vertical orientation, and a similar spec LG TV from 2019 that does the same. Both are better than TN panels but still make it hard to look at while standing or laying down.
