I try and respond when I receive an email letting me know there is a new message. I don't always seem to get notified and then miss a bunch. if you PM me, I don't get notified at all until I am on the forum.
If you don't see any difference between 4:2:2 and 4:4:4 (player setting) then stick with 4:2:2. Dolby Vision is always output as 12-bit 4:2:2 anyway. (or 12-bit 4:2:2 pretending to be 8-bit RGB when in TV-led) In theory, 4:2:2 and 4:4:4 should be identical. At the end of the day, everything converts to RGB in the end and there should be no difference.
We have added an HD version and an HFR (59.94) version to the next disc. Some players only output 59.94 as either 8-bit or 4:2:0 and now you can see if there are visual changes when going from 24 to 60p.
The player output is different than the PC/4:4:4 mode in the OLED mentioned above. Is there a graphics picture mode on the Sony OLED? That might be the one that forces 4:4:4 on Sony. I like to use either the chroma crossed zone plate OR the RGB legal Cb zone plate. I usually set to 10,000 nits as well since that is the brightest version of the pattern. Those two I find the easiest to see the dimmer sides.
The center has thicker lines, which means lower chroma resolution. As you move to the outside (far left and right) the lines get thinner. This is higher chroma resolution. Ideally you want equal brightness from thick to thin lines, which means no loss in chroma resolution.
The chroma diamonds are to look for chroma alignment (YC delay issues). Have you looked at the samples in the
Choosing a Color Space article? There are horizontal and vertical diamonds. The horizontal diamonds are looking at 4:2:0 to 4:2:2 conversion. The vertical diamonds look at 4:2:2 to 4:4:4 conversion.
BT.601 (SD) and BT.709 (HD) have a different chroma layout than BT.2020. Here is an image to visually show you. The white circles are Luma and the red squares are chroma:

In the horizontal direction, chroma is co-sited with luma for 601, 709 and 2020. In the vertical direction, chroma is interstitial (in between) the luma samples for 601/709 and is co-sited for 2020. When you upsample, you have to account for this location or phase. If you don't handle the proper chroma sample location when you upsample, you end up with luma and chroma not being aligned correctly. This can cause one edge to be soft and fuzzy nd the other edge darker. The chroma diamonds and the red on yellow help to see this.
I like to use the Chroma Alignment (Num) pattern to find out the exact amount of delay. This pattern lets you look at both in 0.5 pixel increments. At UHD resolution, you really need a loupe to see the pixels. At UHD2 (7680x4320) you MUST have one. Simply find the diamond that is the most symmetrical and that is the amount of delay/error you have.
As it turns out, you need to check this for SD, HD and UHD in SDR, HDR10 and Dolby Vision. While testing the new disc, I noticed that Dolby Vision HD is off vertically but Dolby Vision UHD is fine.
How do you fix this? A new player, display or both! It is bad processing and not something you can calibrate out.
I hope this answers your question. If not, please let me know.
