So, having about six days to return the UBK90, I’ve ordered the UBD820 to compare the two (almost) side-by-side. I will compare upscaling and dynamic range/PQ of the two. The only 4K DVDs I own thus far are “Into the Spiderverse” and “Dynasties.” I will likely borrow a friend’s copy of “Into the Spiderverse” for direct comparison.

SDR2020 and/or Optimizer and/or Dynamic Range Adjustment and/or Tone Mapping (TV Type) are the only reasons to own a UB820 so play with them all.
Yesterday was the final day to return my UB820.
I've spent as much time as possible (not nearly as much as I'd like) over two nights doing a comparative analysis of both players using Mad Max Fury Road, during the storm scene at around the 28 minute mark (esp. 28:27-28:38).
I will say that spending so much time scrutinizing this movie frame-by-frame leaves me immensely impressed with the level of detail that went into this movie. I dare say, you miss quite a bit by NOT viewing it frame-by-frame (at least in the storm scene)... though I don't expect anyone to take the time to do that.
I did not change the display-type settings on the UB820, but cycled through the HD Optimizer's sliding scale for comparison. I found that when I slid the HD Optimizer below the base-setting, the blacks would begin to darken as well... if only with a very slight gradation.
I messed with the UBK90 settings as well, finding that the "Movie" setting (I think it's called) had the most similar effect to the HDR Optimization the UB820 was performing. I was using the 28:27 mark (car explosion with a man hanging from the front of the car, in the air of the storm) and having a very hard time telling the difference in a substancial way.
That is, until I forwarded, frame-by-frame to around the 28:38 (??) mark. A truck was exploding and the explosion was beginning to engulf another man. I examined a black/dark grey/brown, sandy storm wind/cloud, portion of the same scene near the right edge of the screen and noticed that the UBK90 (on cinema settion) was slightly crushing the blacks where the UB820 was not.
Then, kind-of the dealbreaker, the silhouette of the front of the truck (also being engulfed) was visible in the explosion in red. On the UB820, there were around four distinct shades of red, while on the UBK90 there was only around one, maybe two.
The sound also seem clearer, a bit brighter, on the UB820.
The next day, yesterday, right after work, I took both players back and anguished back and forth over which one to return in the Best Buy parking lot for a minute or two. I even began to take the UB820 into the store.
The dog was confused.
I took back the UBK90. They did indeed take it back, even though the time to return the UBK90 had expired, after explaining I was keeping the more expensive product after testing them. Note: Their return limit exemption policy seems pretty
liberal. Halfway through explaining it, I asked the girl behind the counter if she needed to hear this (my lengthy explanation). She replied, "You can go ahead and tell me," like she just wanted to know, you know, personally.
I'm still uncertain the difference in the pictures warrants the cost, and am not ENTIRELY certain it will be noticeable most of the time. But, the fact remains that I know there is a difference... and I did see it.
That, coupled with the annoyance of UBK90 turning on seemingly at random and hijacking my AVR.
I wish I would have had time to do even more testing. But with what little testing I did, I can only conlude that it was a sample portion indicative of other notable variances I would have come across within different scenes, titles, ranges/gradiants, etc.
Thank you, gentlemen, for your help.
