TN & VA Gamma Shift
TN panels suffer from vertical gamma shift: their colors and shades are uneven from top (top quarter is too dark) to bottom (bottom half is washed out), as well tend to have more banding, and always have vastly less wide, or more restrictive viewing angles, though all LCD panel types look the worst when viewed from above, or looked down at.
VA panels suffer from horizontal gamma shift which causes the sides of VA panel to be significantly lighter or washed out compared to AHVA, IPS and PLS panels. VA panel gamma becomes lower, and colors and shades become more washed out the further away from the center.

All VA panels suffer from black crush when viewed head on, and reveal detail when viewed off angle horizontally. Some VA panels are worse than others, and this issue is less obvious when viewed from far away, but all VA panels suffer from obvious black crush. Also note that the Samsung 43NU7100 has nearly perfectly linear 2.2 gamma and a semi-glossy coating while the Samsung F2380MX has slightly too low gamma (non-linear gamma below 2.2) and is matte.

AHVA - IPS - PLS VS TN
All TN panels have very restrictive viewing angles and suffer from vertical gamma shift, therefore all TN panels have bad image quality. AHVA/IPS/PLS panel glow is not a problem if viewed correctly, and not in the dark with the brightness cranked:
IPS vs TN: Right & Wrong Ways To Use Or View;
How To Vastly Reduce AHVA/IPS/PLS Glow & Increase The Perceived Black Depth
Since TN panels suffer from vertical gamma shift, their colors and shades are uneven from top (top quarter is too dark) to bottom (bottom half is washed out), as well tend to have more banding, and always have vastly less wide, or more restrictive viewing angles, though all LCD panel types look the worst when viewed from above, or looked down at.
It does not matter if one sits directly in front of their TN panel (correct way to view a TN), or how much one pays, especially since the majority (excluding Dell S2716DG & S2719DGF) of the most expensive 27" 1440p TN panels use grainier/sparklier matte coatings than AHVA/IPS/PLS panels. Calibration can vastly improve inaccurate TN panels, but a TN is a TN, and all TN suffer from obvious vertical gamma shift.

Calibrated but connected to a PS4 so there's no gamma correction; both monitors have non-linear and low-ish gamma below the target of linear 2.2
