I don't think the chipset for the 85 and 80 is correct here, most sites are reporting its the X1 (Prob 2020 one), not the X-Reality Pro.
Regardless, this worries me tbh, why haven't they pushed the X1 Extreme and X1 Ultimate down the lineup to make the low end models in 2021 look as good as top models from only a year or two ago? Not in terms HW factor like the backlight or panel ofc, but the software presentation.
I could see how its to make the new stuff look better, but it also makes me think the new XR chip might be a downgrade from the X1 Ultimate, the "2020 X1" and now this feels like some general downgrading going on possibly.
Otherwise its that the 80 and 85 series have the same processing as the 90 from last year but all models above that jump up to something better than X1U, so an X90J has the same software presentation as the flagship OLED? I guess they could also just be calling them all XR but they are actually (more) different across models now.
