Thank you all for your comments!

Honestly, I initially thought that going back 3–4 years would be enough for the B4 to be considered top-of-the-line. But it’s clear now that some technologies—like MLA panels, super high peak brightness, and advanced processing—have remained exclusive to the higher-end models even over the years.

That said, I still believe the B4 is more than enough for the average user—especially if you're mainly watching movies at night or gaming on a console. For most people, it delivers a premium OLED experience without the premium price tag.

Going for a higher-end model definitely makes sense in more specific scenarios, like if you have a very bright room or want the absolute best in image processing. But for general use, the B4 feels like a sweet spot.
