tell us more David!
Was it that the seating distance made the pixel upgrade moot?
Or that the Oppo 203 upscaler is really nice?
We used The Martian and The Magnificent Seven for comparisons. We didn't use the OPPO 203 Upscaler. We compared from the HTPC with Blu-ray to the OPPO with UHD Blu-ray. This way we could just switch inputs and user mode on the projector for fairly quick comparisons. The HTPC had a 1000 point 3D LUT loaded which made the image measure almost completely perfect. This provide a true reference for comparison.
1. At JVC's training I attended in Olathe on their new 4K laser they said that from more than ~3 ft from the screen, 4K on the 4K projector and eShift on a RS500 is indistinguishable when both are fed a 4K source.
2. A UHD Blu-ray has BT.2020 color space. The projector can't display the entire color space (and RS500 does much better than RS400). This give minimal improvement.
3. A UHD Blu-ray has HDR. The projector has only about 1/10th to 1/40th the light output necessary for HDR depending on how they were mastered. This means most of the image is too dark. To make the image a comparable brightness with a Blu-ray makes the gamma and color incorrect. This can maybe fixed with more calibration, but since the UHD Blu-rays are mastered different you have a moving target.
3. If you strip the HDR metadata, the playback device has to decide how to convert the brightness coefficient while preserving the color. There is no standard for this so each device uses whatever algorithm the company has developed. The latest firmware for the OPPO improved metadata stripping, but still doesn't come close to matching a Blu-ray's gamma and color.
4. Using the madVR renderer in JRiver to upscale Blu-ray to 4K using the new NGU (Next Generation Upscaling) algorithm provides the best image quality and experience. I've tested at home and it is better than the OPPO 203 upscaler or the JVC upscaler.
5. A much smaller screen with the projector closer to the screen can help minimize the current negatives with HDR. I watched The Magnificent Seven completely with both UHD Blu-ray and Blu-ray on my own system. I like the highlights offered by HDR but overall prefer the image depth of Blu-ray with its much lower black level (you don't have to be in high bulb with iris open).
