MPG272URX - tandem OLED?

I've noticed MSI's been advertising their latest 272URX model as featuring tandem 5-layer OLED.

Does that produce any brighter picture than other QD-OLEDs?

I'm thinking whether to go with the MPG322URX or stick to the 272URX. The higher PPI on the 272URX isn't really a concern for me as I sit far away from the monitor and prefer to easily split screen when doing productivity work.
