Interesting. Explains a lot.

Sorry, I meant to say that not all those things are true for all titles, just some combination. Mainly coming down to the fact that 1080 is 1080 and the source of a Blu Ray isn't necessarily better (or even as good as) than the source fro a DVD.

Not if you're talking about MPAA releases of MPAA movies.

There are blu-rays mastered from SD sources. As far as I know, most of these are anime (or other niche) releases mastered from the best sources the releasing company could get. These actually tend to look much better than DVDs, due to the higher bitrate and the natively progressive format.

If you're curious about whether a particular release is "really HD", you can check blu-ray.com. Their reviews include that technical information.

There was a show I used to watch that would that would announce the Bluray releases for that week (back when it was less than a dozen per week). They would tell you the codecs used and the quality compared to older DVD releases. There was a good amount of them that simply seemed upscaled from 480p to 1080p, while some of them were cleaned up frame by frame.

Star Trek TNG seasons 1 & 2 on Bluray look far superior compared to the DVD releases. You could probably downscale the HD versions to 480p and still look better than the original releases. I think the Wizard Of Oz also was cleaned up very nicely for Bluray. These were also shot on film and not digital though.

That's actually outdated information, btw.

As someone mentioned and particularly if one never paid for Premium Cable Content (much of which is quite a cut above "mindless crap") Netflix is a bargain, IMHO. Although I am debating whether to get landline phone service, presently I only have DSL internet coming into this house. I've heard there are services to get premium TV over the air but I haven't been enough interested to seek it out. Between Netflix and Amazon Prime, I'm pretty happy though I do miss the option of the latest HBO, Showtime and Starz series. Amazon is far more up to date than Netflix but both are a decent value. As for 4K, like most graphics advances, Gaming is the test bed.

I agree with you about DVDs. Off the top of my head, I can think of four shows which Netflix used to have and either I or someone in my family has ended up purchasing - Stargate SG-1, Stargate Atlantis, Farscape, and Chuck. Netflix is just unreliable in that regard. Besides, when you own the physical media, you have offline access, which can be very useful.

Admittedly, I bought Stargate SG-1 and Farscape on iTunes, so I'll end up having to repurchase them on DVD eventually. In the meantime, I've been watching them on my 2nd generation Apple TV.

Bought a 55' 4k LG OLED TV (curved, because it was 1000$ cheaper than its flat brother having the exact same HW) a few months ago (because my old Sony LCD died).

"Curved" in my case is ok but only because by pure luck my couch is exactly at the right distance (3M) => buy "flat" if you can.

First time I bought a LG-device.
Its upscaler & OLED panel are good, but they shine only if the movie's bitrate is high (I rip my blurays, put them onto my NAS and connect the TV through "MiniDLNA" => basically a 1080-movie-file to be at least 20GB big to look veeeery good on this TV).
OLED is good (I had a "new experience" watching again e.g. Pacific Rim, Arrival and The Dark Knight Rises, but I am most probably not objective as my 10-years-old LCD at the end of its life was veeeery dark).

4k material so far doesn't exist for me - don't want to buy a 4k-bluray player as I cannot rip 4k-material to then save on the NAS as the encryption hasn't been cracked yet, nor can download it for the same reason.
Watched some demos, but wasn't thrilled compared to the SW-upscaler of LG's TV.
Downloaded a h265-stream from Astra's satellite of a Bundesliga soccer match (5 minutes needed something like 1GB, wow), but it looked quite crappy with sections of the public watching the game getting stuck from time to time due to compression artifacts.
Btw. I read that many 4k-blurays have special effects rendered in 2k and upscaled.

I actually bought the TV for HDR, but apparently HDR is available only in 4k-formats, so I'm kind of stuck until 4k-blurays are cracked.
Even in a best-case-scenario of 4k-blurays being cracked now, there is this format-war going on of HDR vs. VisionPlus vs. HDR10 etc... => terrible, thought that it was bad when it was bluray_vs_hddvd but now it's worse.
I didn't even try to connect a PC to the TV to test HDR as I didn't quite understand BT.2020 vs. X vs. drivers etc... => sad.

Wrapping it up:
happy about the TV, but unhappy about the standards.
I bought the 4k TV only because my old one died => I would say that currently 4k is irrelevant, same thing for HDR.
OLED or not? I did definitely want an OLED-TV even after seeing the good picture of my parent's new Samsung 4k-LED-LCD TV (well, their old LCD Toshiba died as well), and I can recommend to go for LED-LCD (apprarently called QLED by Samsung nowadays?) if you're going to watch TV in a bright room, otherwise I would tend to go for OLED if the price difference is low (and otherwise it's more some kind of "religious" approach - I wanted to be pure, therefore I chose OLED, hehe).
LG's OS "WebOS" is quite good - I like it and it worked perfectly so far. Remote (with gyroscope, puaaaahhhh) is as well quite good - don't have any medium nor major complaints.
Cheers
