It's one thing to have a panel that is tuned well from the factory for a single overdrive mode VRR experience but no Freesync designations require.
That is definitely the biggest one I'm aware of, and yeah, it definitely needs to be fixed for
all LCD implementations.
That's really as close as you're going to get at this time, and mostly because Samsung has managed to build 'hybrid' panels that split the strengths and cover the respective weaknesses of both VA and IPS.
I get that this inherent to IPS, but it's also inherent to LCD technology, and the intensity varies between panel types, between panel quality levels, and even between brightness settings and content being displayed.
For example, my XPS 15 has a VA panel that has gobs of noticeable backlighting in normal usage - at its lowest brightness settings, like < 20%. I regularly drop it to 5% for low-light usage and wish it'd go even lower. Crank it to 25% or more, it goes away.
For another example, I have Alienware's (Dell's, with an LG panel) AW3821DW. This is a relatively premium monitor, and has far less IPS glow than most would expect. At the same time it definitely doesn't have a strong HDR presentation and contrast is limited, but color accuracy and consistency is very high, and along with the format (38", 3840 x 1600, 144Hz 8bit or 120Hz 10bit) is why I picked it up over a Samsung panel.
I'd also considered OLED, I just didn't like the compromises. If I primarily gamed on the system I'd be less concerned!
