These don’t seem to be particularly new panels. $600 and only 97% of the sRGB color space (= ~78% DCI-P3), meanwhile a similarly priced LG “QNED” can do 90-95% of DCI-P3. I’m not sure you can even call those TVs HDR if they’re only 8-bit color. None of these models can even remotely compare to a brand new OLED TV.
Ironically HoloISO also can’t be installed easily right now since all the prepared downloads are missing. You could maybe built it yourself from source, but I haven’t figured it out…
