The rollable OLED sounds quite interesting. The only thing I worry about is the motor. Just another thing that can break. It would be nice if LG has a seperate warranty on the motor, say at least 5 years.

At previous CES2018, LG also claimed the rolling mechanism was good for 50,000 cycles of rolling and unrolling. Is that acceptable?

That is mentioned again in this CNET article. But it seems to be implying the screen itself, not the extension hardware.

LG says the TV has been tested to 50,000 rolls up or down. So if you turned it on or off eight times a day it would last 17 years. I asked whether LG would offer additional warranty coverage on the rolly-uppy bits and company reps said that hadn't been determined.
After reading comments from AVSForum and looking at the video posted from Digital Trends, it seems like it’s difficult to match the colors, and other image factors, between the modules that makes up the Samsung 75” MicroLED display, hence why the seams between each module are somewhat visible (you can even see them in the video). Who knows if that’ll be the case for the consumer version.

Why would LG only say the TV screen has been tested to 50,000 rolls up or down without taking into account the mechanism that performs that also with an upcoming consumer release?

Hisense ULED XD 4k HDR with 2900 nits. Has anyone ever heard of this tech before where instead of local dimming, they use a second grayscale 1080p LCD screen in front of the full array backlight? Sounds interesting.

Yes! This is what's used on certain pro LCD monitors to give them insane 1,000,000:1 contrast e.g. http://flandersscientific.com/XM310K/index.php, as well as theatrical Dolby Vision projectors: you align the two 2000:1 panel/chips and the contrast of one is multiplied by the other, I never thought I'd see this on a consumer level display. Doesn't mean that Hisense's application of it is any good, but it's VERY interesting nonetheless because it means that these panels are being made affordable for tech manufacturers to use in consumer products, and using a 1080p panel just for the greyscale part is a shrewd move as it doesn't really need to be 2160p rez.
[edit]
Penton mentioned in the HDR discussion thread that Sony will be migrating their BVMX300 OLED mastering monitor over to one of these dual LCD panel doohickies, so as to provide the same sort of contrast and black level BUT to also provide higher peak brightness and cut down on image retention problems.
If Sony came out with one of these for the consumer TV market, oh boy...

I will take a 5 year warranty over their claim of 50,000 roll ups and downs.

So would having a 1080p grayscale filter be equivalent to a 2 million zone FALD? It sounds like a great stopgap in between LCD and emissive LEDs. Could be very impressive if done right.
Introducing Panasonic’s UB450 and UB150 Blu-ray Players with HDR10+ and Dolby Vision™
Quote:
Two new Ultra HD Blu-ray players with support for HDR10+ dynamic metadata (UB150/UB450) and Dolby Vision (UB450)
Compatibility with Dolby Atmos® [DTS:X] home cinema sound systems
Support for wide range of media formats gives maximum flexibility
7th January 2019 – Panasonic today announced the launch of its latest Ultra HD Blu-ray players, the DP-UB150 and DP-UB450 series, with both models supporting HDR10+ dynamic metadata technology and the UB450 series also offering Dolby Vision. By optimising the brightness of each image, scene by scene, these cutting-edge HDR formats faithfully reproduce HDR images that faithfully match the creator’s original intentions. Thanks to these image-optimising technologies, both the DP-UB150 and DP-UB450 series deliver a highly cinematic experience with richly textured images.
Both players feature Dolby Atmos compatibility, enabling you to enjoy an exceptionally immersive 3D soundstage with a compatible audio device such as a TV, soundbar or AV receiver. In addition to conventional surround sound, Dolby Atmos uses height channels to precisely place sound effects or the sounds of individual objects at or above ear level. Paired with an audio system that can decode Dolby Atmos, the result is breathtaking movie sound from the UB450 and UB150 series.
The addition of the UB450 and UB150 series to Panasonic’s UHD Blu-ray family follows the recent launch of the highly acclaimed 'EISA High-end UHD Blu-ray Player 2018-2019' reference model, the UB9000 Series.
Stunning picture quality from 4K/HDR content
Support for HDR10+ dynamic metadata technology and Dolby Vision
Both players feature HDR (high dynamic range), which has a wider, brighter dynamic range than conventional SDR (standard dynamic range) to produce more natural, more lifelike images when viewed on an HDR compatible TV.
More than that, both models are also compatible with HDR10+, the latest version of HDR, which uses ‘dynamic’ metadata to re-optimise the brightness continually throughout the movie rather than sticking to a single ‘static’ setting. The result is the ultimate home cinema experience, with even more dynamic, colourful and realistic HDR images that precisely match the creator's intention. In addition, the UB450 supports Dolby Vision, a similar alternative to HDR10+. With the UB450 UHD Blu-ray player and a compatible TV (such as the new Panasonic GZ2000) consumers are assured of seeing fully what the filmmaker intended, regardless of which dynamic HDR format has been used.
4K camcorder video and JPEG playback
4K videos (MP4 format) made with a camera or camcorder can be reproduced using Panasonic's 2019 Ultra HD Players, while JPEG data can be output in 4K resolution so users can enjoy the memories of vacation trips in all their natural beauty.
High Quality Sound: Unique audio technologies achieve rich sound reproduction
High-Resolution Audio playback from a wide range of formats
Panasonic’s new Ultra HD Blu-ray players are equipped with High-Resolution Audio reproduction. In addition to conventional MP3/AAC/WMA formats, additionally high res audio music files such as DSD (11.2MHz/5.6 MHz/2.8 MHz) ALAC, FLAC, WAV and AIFF can be reproduced. Simply by connecting to a home audio system users can enjoy music sources with the unmatched studio master sound quality.
Twin HDMI Pure AV (Audio/Video isolated twin HDMI)
The UB450 series and UB159 model feature dual HDMI outputs for isolating and separately transmitting TV (4K video) and amplifier audio. By separating audio and video signals unwanted noise is suppressed, which results in the highest-quality sound reproduction. The Player can also output the latest surround formats including Dolby Atmos*. When using a sound system compatible with Dolby Atmos soundtracks, it creates the most sonically immersive soundstage available.
HDR10+ is an open, royalty-free dynamic metadata platform created by 20th Century Fox, Panasonic and Samsung. To learn more about the HDR10+ license program, please contact the HDR10+ license administration office at info@hdr10plus.org.

Very cool stuff. But yeah, unless by some miracle reviews for Hisense's models are great, I'll wait for a different (better) company to implement it.
