YES, the new model is going to be Much Better.
"The new P-Series Quantum X 4K HDR TV is all about brightness. It features an absolutely retina-searing 3,000-nit peak brightness capability, which should take HDR material to an intense new level in terms of realism. Vizio claims the quantum dot panels used on the P-Series Quantum X are the highest performing on the market, offering 180% more color than standard 4K HDR TVs.
Depending on screen size, the P-Series Quantum X has up to 792 local dimming zones, which should prove highly capable at ensuring deep blacks with minimal halo-effect on even the most complicated of scenes.
This model shares all of the processing technologies found on the OLED 4K HDR Smart TV, including the IQ Ultra processor, ProGaming Engine, and support for HDR10, HDR10+, Dolby Vision, HLG, HDMI 2.1, and HDMI eARC."
