You REALLY should reconsider it, if you're serious about motion performance as the ~0ms response times coupled with the lack of any pixel overshoot will result in each new drawn frame fully transitioning over from the previous one in a given refresh cycle window faster with no settling time and therefore resolving to cleaner apparent motion with less blur than almost any e-sports TN panel (most all of which are only 1080p). See picrel.
Moreover, because of the effective instant response times you can then use CRT Beam Simulation shaders to force a refresh of the image to further retina persistence of modern sample-and-hold displays which is not something most LCDs can accomplish.

You already have an IPS LCD so just run it as your primary desktop/browsing display and then switch over to your OLED for gaming/video in a dual setup if burn-in worries you (easy 8-10 years of lifespan that way). Plus there's the advantage of perfect colors/contrast which TNs are notoriously poor at it.

>but on the topic of blurbusters, what am I supposed to do from that website?
Read in-depth articles on monitor motion and new technologies to improve it? Also use the UFO Test to check your displays real motion performance (there are many test parameter options available in the top menu scrollbar and make sure you close all other apps beside the browser to prevent errant latency from causing window sync glitches with your display's native refresh rate).
