@nowaynews Well, it depends on the exact implementation of the backlight. But yes, to some extent that can be true (though definitely not to this extreme!) But that's only one specific part of the three so it still threw me off because it's as if it's saying IPS is just all around duller and less saturated... IPS is actually very colorful. Sometimes tuned to be too much so if anything. TN panels, on the other hand, absolutely would qualify to be like the left cat compared to the right cat (even when compared to IPS.) There's a reason IPS suddenly made a comeback as everyone realized.
As far as backlights go, bleedthrough really depends on implementation. I have one IPS panel with really good blacks and barely any bleedthrough and I have one that's terrible.
