However I agree with you that the upscaling has gotten better but you have to also take into consideration that the amount of upscaling needed to be done on an 8k tv is also astronomically bigger so it didnt improve in a linear fashion.
But , to say that an upscaled image improves picture quality over a a native one is just simply false.
Interesting discussion, and without a dog in this fight, I'd like to take the devil's advocate and argue in favor of upscaling based on its technical merits:
1. Assume 75" TV showing 1080p source material.
2. Assume you have both a native 1080p 75" TV and 8K TV upscaling the 1080p source material
3. Assume everything else is level matched to be equal (color volume, brightness, SDR, etc.)
4. The native 75" TV has literally 1080p number of pixels, and every pixel simply displays the exact match from the 1080p source. This ensures that the 75" TV represents each and every source pixel fully and accurately as intended. However, 1080p pixels are significantly larger on a 75" TV; thus, if the pixels are round/circle shaped dots, then there will be gaps between each pixel dot, but if the pixels are square to eliminate the gaps, then there will be also be visible pixelation/macroblocking visible on the 75" TV due to the lower resolution.
5. The 8K 75" TV has more pixels (16x more) than the 1080p TV, so this 8K TV will use 16 pixels to represent one 1080p source pixel. So this is where the magic happens and the crux of our disagreement! Those who are against upscaling - they believe that there is no way 16 pixels can be properly calibrated/directed to better a single 1080p pixel. The pro-upscaling side argues that having 16 pixels means you will never have visible pixelation because each 8K pixel can provide a smoother gradient to fill in the spaces between each 1080p source pixel.
My conclusion: 75" 1080p native panel will ALWAYS have gaps that are visible between the pixels - there is no solution to overcome this - you're trying to fill a larger panel with 1/16 the number of pixels, how does that work?8K upscaling gives the "opportunity" to fill in those mixing gaps with the right upscaling algorithm (whether AI or whatever) so that the gaps between each 1080p source pixel appears more natural than the pixelation of 1080p.
What anti-upscalers fail to understand is that upscaling is essential for large screen TVs!
