This seems to be the conclusion I have come to after performing the test quoted below.

Being that there is no way to turn off the upscaling on the UBK90 and that I’m giving my old HTIB to my in-laws, this is annoying for the remainder of my collection.
I’ve also learned about the UBD820’s tone-mapping capabilities and am curious if I’d see diminishing returns/competing interests in that regard when coupled with the LG OLEDs capabilities for the price.
Asked a similar question on the UBK90 Owner’s thread with no response.
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.
I’m pretty new to all this so am looking for advice on how to test the two platforms, comparatively (i.e. what settings to use, test pictures to view, scenes to examine, etc.). I am a Netflix <edited> member, so I can view the Altered Carbon scene referenced in an earlier post <2nd episode: 47 second mark>.
With what limited time I had over the weekend, I performed as much comparative examination as I could with “Spiderman: Into the Spiderverse,” “Man of Steel,” and “The Hobbit.” “Man of Steel” had a very useful “Pacific Rim” preview that I utilized as well, with several snow and rain scenes, which are apparently(?) notorious for causing imaging problems.
I also viewed the scene from Altered Carbon, in still frame, mentioned above.
Man of Steel (1080p) has a considerable amount of grain and is not shot very well in certain scenes, such as those out at sea.
While upscaling of Man of Steel was slightly better on the UB820 resulting in less grain and better picture for out-at-sea scenes, upscaling on the UBK90 was not as poor (or noticeably different) as originally thought.
No notable difference was found in upscaling of the Hobbit, upon cursory examination of the scene revealing Smaug’s missing scale.
The UB820 revealed more clarity of detail in the upscaling of snow and rain scenes in the Pacific Rim preview, though likely not as noticeable to the less discerning eye.
Spiderman: Into the Spiderverse, mastered @ 4000 nits, showed no readily perceivable differences between players in motion scenes. Special attention was paid to inter-dimensional scenes, Miles getting bit and the morning after at school, The Prowler and Miles’ scene in the apartment, pearlescent reflections in Parker Spiderman’s and Spiderwoman’s eyes in the bread scene, and the final battle. The largest perceivable difference was in the title menu; Miles’ spider symbol in the middle of his chest seemed slightly brighter/more vibrant on the UB820 while slightly (almost imperceptibly) diminishing small variances in shades of red within that symbol. Red seemed slightly brighter on action scenes throughout, upon noting this.
A bug slowing the connection of the UBK90 to the internet (had trouble connecting to the wired internet) prevented me from examining Altered Carbon to the extent desired, but upon cursory examination, there seemed to be little, if any, difference of the 2nd Episode, 47th second image.
UB820 was the clear, obvious, and widely known winner, both aesthetically and functionally. Though, the functionality of such an in-depth user interface seems rendered obsolete with the high functionality of the LG OLED65B7P’s user interface.
The UB820 was peculiarly more sensitive to dirt/abrasions. Man of steel froze in one spot, a small, fine scratch, remedied without skipping content once the “forward” button was pressed on the remote. There have been no freezes or interruptions in video playback on any content yet played on the UBK90.
The UBK90 will randomly turn on. Also, while previewing content on the UB820 with the UBK90 on, the Marantz receiver would automatically, and seemingly at random, switch input to the UBK90 without any content playing on the UBK90.
The UB820, freezing upon stopping of a DVD (display said “STOP” yet no image broadcasted), was turned off and on several times trying to regain image. The second time it was turned on and off, the display came on as green with a multi-colored vertical band through the screen. After unplugging it for 15 seconds and plugging it back in, player resumed normal function.
As mentioned previously, the UBK90 experienced some difficulty finding the wired network after switching from wi-fi.
No perceivable difference was noted in the sound quality of any content played. No audio CDs or other strictly audio formats were used as comparisons. Content was listened to using Audyssey XT32, Flat response, all other options (e.g. Dynamic Audio, etc.) off.
Based upon my comparisons, the equipment chosen by those most active in this forum (most of the UB820 owners seem to be seeking the tone-mapping for use on their projectors with <1000 nit capabilities), feedback to projector-related issues/questions on this forum, and lack of feedback to OLED-related issues/questions on this forum, it would appear there is no sufficient perceivable difference between the UBK90 and the UB820 to warrant the additional $300 expenditure for use with an LG OLED65B7P.
Since the tone-mapping ability of the UB820 is one of the three features (along with upscaling and hi-def sound?) supposedly setting it apart, the LG OLED65B7P is already rated at around 1,000 nits, Into the Spiderverse was mastered at 4,000 nits, and the difference in PQ between players on Into the Spiderverse is de minimis; my only remaining question would be whether there is a perceivable difference in the tone-mapping of a movie mastered at 10,000 nits vs. 4,000 or 1,000 when viewed on this display.
If time allows (which is unlikely) and if it is available at Redbox, I would like to rent a 4K Blade Runner 2049, mastered at 10,000 nits, to view on both players. Today is the final day to return the UBK90, so I will likely be keeping it, returning the UB820, and using some of the money to build floating shelves for my towers.
