Not exactly the same engine, but these photos are from a 11 Accord 2.4 with about 110k. This engine has only seen 10k oil changes. Most were with EP 0w20, but some were with other brands of 0w20 synthetic. You be the judge.

But is it cleaner than conventional at 5K? Somewhat. But probably not enough to matter
The 11 drank about 1 qt every 8-9K.
With different lighting it's hard to compare but the syn looks better but they are different engines, operating environments, etc. So many variables ...
Based on pics, I would go with the syn. The 10K oci alone is saving you time and money vs. the 5K oci. Also theoretically syn is better than dino ...

Looks good!
You're looking at VTECH cams. There's only one lobe for intake/exhaust, the third lobe is switched in and out by the ECM and takes over for the 'regular' intake lobe (or is it exhaust, I can't remember off the top of my head)

Looks good but are both engines ran the same? One could be much more wide open interstate or more stop and go.
The 11 saw mostly highway driving. 07 is mostly city.
Thanks as that is why oil change interval is not universal. In my particular case I have tried to come up with an interval and a oil but can't settle. Owners manual states 4k severe and OLM regular or 10k 1 year. I did 6 months which's comes out 3.5k. These pictures (different motor) just confirmed my experience.

That’s great.
What oil was used? Same oil and filter or different combos over the year?

for majority of its life it was dino oil used by variety of manufacturers with 5W-20 grade as same as goes for the oil filters; however, I was changing oil for 3K religiously; around 200K mark I started to used 5w-20 synthetics. Keep in your mind I was not original owner of the car; I inherited it at 49K miles; originally, it was registered in NY state as a fleet car; Super smooth car to this day
honestly, a variety of oil brands but I stuck to 5W-20 only over the years; It is testament to that MZR engine by Mazda since there are more people on this forum who achieved the same results; these engines along with FNR5 transmission are well known for its reliability and endurance in Mazda and Ford products
