Interesting comment, thanks. Two questions out of curiosity: > Even though I have top notch viewing gear properly configured and calibrated Any chance you'd be willing to share a few details about this? > While some pre-compressed streamed film content looks quite good when delivered via a streaming service willing to devote sufficient encoding time and delivery bitrate, it's still hit and miss. Which streaming services are doing things right in your view? |

I have several viewing devices in different rooms including an LG C2 OLED, a high-end Samsung QLED and in my dedicated, fully light-controlled home theater room a native 4K 10-bit HDR+ laser projector and 150-inch screen. Each of these displays has been professionally calibrated. To objectively evaluate an input source these days it's important to try multiple different display technologies because flat screens can vary between OLED, QLED, mini-LED, LCD and VA which all have different trade-offs in contrast, peak brightness, viewing angles, color spaces, gamma response curves, etc. And that's before getting into various front projector technologies.
Most consumer TVs these days come with a pile of post-processing algorithms which claim to deliver various "enhancements." In almost all cases you'll want to turn these options off in the setup menus. For critical viewing, objective calibration with a suitable colorimeter is ideal, especially when considering HDR sources which should be normalized to each display's native capabilities in Nits. If you don't want to dive down the rabbit hole of evaluating all this yourself (which can admittedly get complex), I suggest the TV reviews at https://www.rtings.com which are credible, thorough and yet still relatively accessible to non-experts. Unfortunately, RTings doesn't evaluate front projectors. For that the best bet is an expert forum like AV Science (https://www.avsforum.com).

Currently, I don't think there's any service I would say is universally "doing it right." It still varies depending on the individual piece of content. Amazon, Netflix, AppleTV and even YouTube each have some extremely well-encoded, high bitrate content. But I've also seen examples on each service that aren't great.
The highest-quality home source will typically be a UHD Blu-Ray disc player. If you have such a player I highly recommend the Spears and Munsil UHD Benchmark Discs (https://spearsandmunsil.com/uhd-hdr-benchmark-2023/). Just because a disc is UHD format doesn't mean the media on it has been encoded correctly, from a high-fidelity source and in appropriate quality. The Spears and Munsil disc features a comprehensive suite of custom-designed test signals and specially sourced demonstration content identically encoded in HD, UHD, HDR, HDR10, HDR10+ and DolbyVision, including moving-window split screens allowing you to compare formats. It's extremely impressive and, as a video engineering geek, I found it fascinating to explore for hours on my various displays - while my wife had zero interest in it :-).
